  1. "An expression for the charge-deposition distribution near the surface of a semi-infinite medium irradiated by electrons." F. Alouani-Bibi, V.T.Lazurik, Yu.V. Rogov and T. Tabata, IEEE Trans. Nucl. Sci. Vol. 46, No. 3, pp. 280-283 (1999) (doi: 10.1109/23.775528).
    Abstract: On the basis of the characteristics of electron transport, a semiempirical model has been developed to describe the charge-deposition distribution due to knock-on electrons produced by electron-electron interactions near the surface of a semi-infinite medium. A criterion is provided for the thickness of the zone near the surface where the charge deposition is essentially due to knock-on electrons. A comparison between the charge-deposition distributions obtained by the Monte Carlo method and the present model is made in the above zone. The absorber materials considered are Be, C, Al and Cu, and the energies of incident electrons are from 1 to 10 MeV. The advantages and limitations of the present model in comparison with other analytic expressions are discussed. (© 1999 IEEE)

  2. "Average depths of electron penetration (II): Angular dependence and use to evaluate secondary-electron yield by photons." V. Lazurik, V. Moskvin, Y. Rogov, T. Tabata, IEEE Trans. Nucl. Sci. Vol. 46, No. 4, pp. 910-914 (1999) (doi: 10.1109/23.790702).
    Abstract: In our previous paper [V. Lazurik, V. Moskvin and T. Tabata, IEEE Trans. Nucl. Sci. 45, pp. 626-631 (1998)] the average depth of electron penetration, Rav, has been introduced as the average of the maximum depths on the trajectories of electrons passing through a target. In the present work the dependence of Rav on the angle of incidence of an electron beam has been studied. A semi-empirical equation is derived to calculate Rav as a function of angle of incidence. We extend the study of Rav from using it to characterize the average behavior of electron beams in a target to describing the generation of secondary electrons by photon beams. It is shown that Rav can be used in a wide variety of applications in which the characteristic size of the spatial region of electron production is important. (© 1999 IEEE)

  3. "Mirror reversal simply explained without recourse to psychological processes." T. Tabata and S. Okuda, Psychonomic Bulletin & Review Vol. 7, No. 1, pp. 170-173 (2000) (Download PDF).
    Abstract: This paper proposes a simple and definitive solution to the mirror-reversal problem, "Why does a mirror reverse left and right but not up and down?" The solution is given by combining the inversion caused by the optical process of mirroring and the definition of the left-right axis. Thus the left-right reversal of mirror images essentially does not involve psychological processes, in contrast to the multiprocess hypothesis recently proposed by Takano.

  4. "Approximation of charge-deposition density in thin slabs irradiated by electrons." F. Alouani-Bibi, V. T. Lazurik, Yu. V. Rogov and T. Tabata, Radiation Physics and Chemistry Vol. 59, No. 3, pp. 239-248 (2000) (doi: 10.1016/S0969-806X(00)00268-1).
    Abstract: Charge-deposition distributions in thin slabs irradiated by plane-parallel electron beams are studied. The slabs considered are made of elements with atomic numbers ranging from 4 to 79. The slab thicknesses are from 0.5 to 50 mg/cm2, and the electron beam energies are from 1 to 10 MeV. Using a new Monte Carlo method (called the trajectory translation method), data on the charge-deposition density have been obtained. Theoretical analysis of these data has been performed. Based on this analysis, a semiempirical model that describes charge-deposition distributions in thin slabs has been developed. The results obtained by the semiempirical model have been compared with those obtained by the PENELOPE Monte Carlo code and show moderate agreement. (© 2000 Elsevier Science Ltd.

    Abstract: Analytic expressions fitted to cross section data on collisions of H+, H2+, H3+, H, H2, and H- with H2 are given. The data used are those recommended by Phelps [J. Chem. Phys. Ref. Data 19, 653 (1990)] and additional experimental data, when available, up to the projectile energy of about 100 keV, including new kinds of reactions not treated by Phelps. The analytic expressions are of the semiempirical functional forms proposed by Green and McNeal [J. Geophys. Res. 76, 133 (1971)] and modifications of these, thus making it possible not only to interpolate but also to extrapolate the data to some extent. (© 2000 Academic Press)

  6. "Charge-deposition in two-layer systems irradiated by electrons." F. Alouani-Bibi, V. T. Lazurik, Yu. V. Rogov and T. Tabata, Radiation Physics and Chemistry Vol. 60, No. 3, pp. 151-156 (2001) (doi: 10.1016/S0969-806X(00)00332-7).
    Abstract: On the basis of the data obtained by computer simulation and theoretical analysis of charge-deposition density in single slabs located in vacuum (Alouani-Bibi et al., 1999), a semiempirical model that describes the charge-deposition distributions in two-layer systems irradiated by fast electron beams has been developed. The slabs considered are made of materials with atomic numbers from 4 to 79 and thicknesses from 0.5 to 50 mg/cm2 irradiated by electron beams with energies from 1 to 10 MeV. Comparisons have been made of the results obtained by the present model and those obtained by the PENELOPE code. Results of charge-deposition distributions for different material combinations of the layers are also presented. (© 2001 Elsevier Science Ltd. All rights reserved.)

    Abstract: A 2.1% discrepancy was reported from an electron beam dose comparison between liquid chemical dosimeters and a water calorimeter. Two methods, depthÐdose measurement in a sandwich phantom and the use of a semiempirical depthÐdose code EDMULT, were used to analyze the depth-dose distributions in the dosimeters and the calorimeter and to calculate their dose ratio. Results have shown that the discrepancy can be explained by the difference in the effective detection volume. (© 2001 Elsevier Science Ltd. All rights reserved.)

    Abstract: Cross section data in the energy range above 1 eV have been critically evalutated for collision processes by electron impacts involving the most relevant plasma impurity species (CO, CO2, and H2O). A short review of the cross section measurements is given for each collision processes. The literature has been surveyed to December 1998.

  10. "Oxygen tracer diffusion in the YBa2Cu3Oy superconductor." S. Tsukui, M. Adachi, R. Oshima, H. Nakajima, F. Toujou, K. Tsukamoto and T. Tabata, Physica C Vol. 351, pp. 357-362 (2001) (doi: 10.1016/S0921-4534(00)01640-3).
    Abstract: The oxygen diffusion coefficient of YBa2Cu3Oy (YBCO) single crystals was determined by secondary ion mass spectrometry in a wide temperature range from 628 to 1073 K. It was found that the slope of the Arrhenius plot of the diffusion coefficient changes at the transition temperature from the orthorhombic to the tetragonal phase (TP). The activation energies of oxygen in the TP and the orthorhombic phase (OP) are 89.1±1.4 and 114.6±1 kJ mol-1 in the ab plane, and 284±2.8 and 126.9±0.5 kJ mol-1 in the c axis direction, respectively. In the OP, the activation energies in the ab plane and the c axis direction are almost the same, but the diffusion coefficients in the ab plane are larger than that in the c axis direction by more than three orders of magnitude. At higher temperatures of the TP, the slope of the Arrhenius plot in the c axis direction becomes larger and the diffusion coefficient of the c axis becomes closer to that of the ab plane towards the incongruent melting point of YBCO compounds.

  11. "Preparation of Bi-2201 thin films Bi2LnxCa2-xCu1Oz (0.4≤x≤0.8, Ln = La, Pr, Nd, Sm, Eu and Gd) by laser ablation." K. Yoshida, S. Tsukui, T. Tabata, M. Adachi, R. Oshima, Y. Mizokawa, Physica C Vol. 361, pp. 189-194 (2001) (doi: 10.1016/S0921-4534(01)00411-7).
    Abstract: We have prepared Bi-2001 thin films of Bi2LnxCa2-xCu1Oz systems (Ln = La, Pr, Nd, Sm, Eu and Gd) by the laser ablation method. In the Bi2LaxCa2-xCu1Oz system, the Bi-2201 films have been obtained in a wide composition range of 0.4≤x≤0.8, and the films with x<0.7 have been of the metastable phase, which has never been reported to be synthesized by the solid state reaction method. The film with x = 0.4 has shown the lowest resistivity in the Bi2LaxCa2-xCu1Oz system, and in the Bi2LnxCa2-xCu1Oz system (Ln = La, Pr, Nd, Sm, Eu and Gd), when x is fixed to 0.4, the film with Ln = Nd has hsown the lowest resistivity. From the results of resistivity and magnetic measurements, however, none of these films have been found to be superconductive. (© 2001 Elsevier Science B. V. All rights reserved.)

  12. "Extrapolated ranges of electrons determined from transmission and projected-range straggling curves." Tatsuo Tabata, Vadim Moskvin, Pedro Andreo, Valentin Lazurik and Yuri Rogov, Radiation Physics and Chemistry Vol. 64, No. 3 pp. 161-167 (2002) (doi: 10.1016/S0969-806X(01)00469-8).
    Abstract: Extrapolated ranges of electrons Rex,t and Rex,p have been determined from transmission and projected-range straggling curves, respectively. Data on the two kinds of curve have been obtained by Monte Carlo calculations for 0.1-50 MeV electrons incident on elemental absorbers of atomic numbers between 4 and 92. The two sets of extrapolated ranges, as well as another set, Rex,q, determined from charge-deposition curves [Tabata et al., Nucl. Instr. Meth. B 119 (4), 463-470 (1996)], have been found practically the same. Appreciable differences of Rex,t from Rex,p and Rex,q have been observed only for electrons of energies below 2 MeV incident on absorbers of the highest atomic numbers. The cause of these differences has been traced to the backscattering of electrons from the incident surface, phenomenon affecting only Rex,t among the extrapolated ranges determined by the three methods. The fact that the extrapolated range is in most cases independent of the method of determination establishes the usefulness of this quantity. An analytic expression fitted to the Monte Carlo results of Rex,t is given. (© 2002 Elsevier Science Ltd. All rights reserved.)

  13. "Dose perturbations at high-Z interfaces in kilovoltage photon beams: Comparison with Monte Carlo simulations and measurements." Indra J. Das, Vadim P. Moskvin, Alireza Kassaee, Tatsuo Tabata and Frank Verhaegen, Radiation Physics and Chemistry Vol. 64, No. 3 pp. 173-179 (2002) (doi: 10.1016/S0969-806X(01)00460-1).
    Abstract: Dose perturbations (backscatter dose perturbation factor, BSDF, and forward dose perturbation factor, FDPF) near high Z material interfaces have been reported to be intense and significant in kilovoltage photon beams. Validity of estimation of dose perturbations is critical in the evaluation of radiation effects associated with high Z interfaces. The magnitude of dose perturbations has been debated due to limitations in the measuring devices (mainly window thickness and chamber perturbations). Monte Carlo (MC) simulations have been proposed for the interface effects but poor statistics in small spatial bins (1 mm) near the interface makes MC data questionable even with a well designed code. A moving-window least-square polynomial fit (MLPF) method is proposed to smooth MC simulated data. This method is shown to be useful in achieving reasonable accuracy from statistically poor MC data obtained within a reasonable computation time. The EGS4 and PENELOPE MC simulated data at the interfaces between high-Z materials and a water phantom have been used to calculate the BSDF and FDPF which differ significantly from the measurements suggesting the necessity of further refinements in MC approaches and better measuring devices for interface effects.

    Abstract: Preparation of Bi2(LnxCa2-x)Ca2Cu3Oz thin films (0.3≤x≤0.7, Ln = Pr, Nd, Sm, Eu and Gd) by the laser ablation method and their physical properties are described. These films have been of metastable Bi-2223 phase, which had not been synthesized by the solid-state reaction method. In the Bi2(PrxCa2-x)Ca2Cu3Oz system, the resistivity of Bi-2223 films has increased with increasing Pr content x, and the film with x = 0.3 has shown the lowest resitivity. When x is fixed to 0.3 in the Bi2(LnxCa2-x)Ca2Cu3Oz systems, the film with Ln = Sm has shown the lowest resistivity. However, the result of the resistivity and magnetic measurements have shown that none of the films is superconductive. (© 2001 Elsevier Science B. V. All rights reserved.)

  17. "Relationship between frames of reference and mirror-image reversals." H. Yoshimura T. Tabata, Perception Vol. 36, No. 3, pp. 1049-1056 (2007) (doi: 10.1068/p5529).
    Abstract: The mirror puzzle related to the perception of mirror images as left–right reversed can be more fully understood by considering an extended problem that includes also the perception of mirror images that are not left–right reversed. The purpose of the present study is to clarify the physical aspect of this extended problem logically and parsimoniously. Separate use of the intrinsic frame of reference that belongs to the object and one that belongs to its mirror image always leads to the perception of left–right reversal when the object has left–right asymmetry; on the other hand, the perception of left–right nonreversal is always due to the application of a common frame of reference to the object and its mirror image.

  18. "Critique of Kokame's article: From comparison with Tabata's article." T. Tabata, Cognitive Sudies, (Part of Highlights: Mirror reversal; Part 1, Kokame's article) pp. 504-505 (2008) In Japanese.
    Abstract: The difference between Kokame and Tabata hypotheses on the mirror problem comes from the rejection of the notion of the mirror image's intrinsic frame of reference by the former. However, this rejection has no solid freason.

  19. "Left–right reversal and nonreversal of mirror images: Solution from physical aspects." T. Tabata, Cognitive Sudies, (Part of Highlights: Mirror reversal; Part 2, Tabata's article) pp. 512-515 (2008) In Japanese.
    Abstract: When one uses intrinsic frames of reference separately for an asymmetric object and its mirror image, one perceives the mirror image as left–right reversed because of such a nature of the left–right axis that it is determined depending on the top–bottom and front–back axes. When one perceives the mirror image as left–right nonreversed, on the other hand, one is applying a common frame of reference to the object and its mirror image, obtaining the simple result of geometric optics.

  20. "Reply to Kokame: Left–right reversal means reversal not in position but in shape." T. Tabata, Cognitive Sudies, (Part of Highlights: Mirror reversal; Part 2, Tabata's article) pp. 520-525 (2008) In Japanese.
    Abstract: All of Kokame's arguments against Tabata hypothesis are rejected as invalid. Instead, those arguments have clearly revealed that Kokame's hypothesis has no reason of its existence.

  21. "Reply to Takano: Criteria for choosing frames of reference can simply be added." T. Tabata, Cognitive Sudies, (Part of Highlights: Mirror reversal; Part 2, Tabata's article) pp. 530-535 (2008) In Japanese.
    Abstract: All of Takano's arguments against Tabata hypothesis are rejected as invalid. Thus the validity and solidity of Tabata hypothesis have been proved.

  22. "Critique of Takano's article: From comparison with Tabata's article." T. Tabata, Cognitive Sudies, (Part of Highlights: Mirror reversal; Part 3, Takano's article) pp. 552-554 (2008) In Japanese.
    Abstract: Takano's hypothesis treats the psychological processes of mirror image perception; and Tabata's, its physical basis. Properly speaking, these two approaches should be united. To make the unification possible, however, the physical conception on which Takano's hypothesis is constructed should be rectified.

    Abstract: The experimental and computational work on the passage of fast electrons through matter done at the Radiation Center of Osaka Prefecture (RCOP) is reviewed. Related topics and problems to be solved are also described. The experimental work treated is the measurement of backscattering coefficients and charge-deposition distributions. Possible causes of discrepancies between experimental and Monte Carlo results are discussed. Among the results of the computational work, an empirical formula for the backscattering coefficient, a semiempirical formula for the extrapolated range and the algorithms for depthÐdose distributions are described. In Appendix, the work on interpolation formulas for the continuous slowing-down approximation (CSDA) range is reviewed, and a new formula is suggested.

    Abstract: Methods to formulate analytic expressions for atomic collision cross sections as a function of projectile energy are described on the basis of the experiences of the data compilation work for more than 20 years. Topics considered are the choice of appropriate functional forms for the expressions and optimization of adjustable parameters. To make extrapolation possible, functions to be used should have the form with reasonable asymptotic behavior. In this respect, modified Green-McNeal formulas have been found useful for various atomic collision cross sections. For ionization processes, a modified Lotz formula has often given a good fit. The ALESQ code for least-squares fits has been convenient to optimize adjustable parameters in analytic expressions.

    Abstract: Institute for Data Evaluation and Analysis; Research Institute for Advanced Science and Technology, Osaka Prefecture University; Shanghai Applied Radiation Institute, Shanghai University; and Department of Radiation Oncology, Indiana University School of Medicine contributed a newly frozen version of EDMULT. Version 6.4 evaluates depth-dose distributions produced by plane-parallel electron beams normally incident on one- to six-layer slab absorbers. EDMULT is based on an analytic expression of the depth-dose curve in semi-infinite medium and a simple model of electron penetration through a multilayer absorber. The effect of the different medium beyond an interface is accounted for by the difference of backscattering, which is evaluated by considering the branching of electron beam into transmitted and backscattered components.  . . .
