| 1 | Gamma-ray and neutron shielding efficiency of Pb-free gadolinium-based glasses显示文摘The radiation shielding efficiency of material depends upon photon attenuation, exposure buildup factors and neutron removal capacity. A newly developed Pb-free gadolinium-based glasses in compositions(80-x) B_2O_3-10 Si O_2-10 Ca O-x Gd_2O_3(where x = 15, 20, 25, 30 and35 mol%) had completely been investigated for their shielding efficiency with Geant4 simulation for mass attenuation coefficients and neutron total macroscopic cross section and by calculating exposure buildup factors.The exposure buildup factors for photon energy from 0.015 to 15 Me V had been calculated up to 40 mean free paths using five factors geometric progression method. The mass attenuation coefficients of the Pb-free glasses were simulated for energies from 223 to 2614 ke V and compared with the possible available experimental results. The neutron shielding efficiency of these glasses was discussed by calculating neutron total macroscopic cross section for energies from 1 e V to 14.1 Me V. Present investigations are found to be very useful for applications in nuclear engineering. | V.P.Singh N.M.Badiger S.Kothan S.Kaewjaeng T.Korkut H.J.Kim J.Kaewkhao | 2016 | Nuclear Science and Techniques2016，27，4： | 1 |
| 2 | Photon interaction with semiconductor and scintillation detectors显示文摘Mass attenuation coefficients,effective atomic numbers,and electron densities for semiconductor and scintillation detectors have been calculated in the photon energy range 1 keV-100 GeV.These interaction parameters have been found to vary with detector composition and the photon energy.The variation in the parameters with energy is shown graphically for all the partial photon interaction processes.The effective atomic numbers of the detector were compared with the ZXCOM program,and the results were found to be comparable.Efficiencies of semiconductor and scintillation detectors are presented in terms of effective atomic numbers.The study should be useful for comparing the detector performance in terms of gamma spectroscopy,radiation sensitivity,radiation measurement,and radiation damage.The results of the present investigation should stimulate research work for gamma spectroscopy and radiation measuring materials. | v.p.singh n.m.badiger | 2016 | Nuclear Science and Techniques2016，27，3： | 0 |
| 3 | Investigating the effect of entrance channel mass asymmetry on fusion reactions using the Skyrme energy density formalism显示文摘In the present investigations,the fusion crosssections for the formation of 200Pb compound nucleus(CN)using 16O+184 W,30Si+170Er,and 40Ar+160Gd nuclear reactions at energies above the Coulomb barrier were calculated to understand the effect of entrance channel mass asymmetry(α)on the fusion reactions;the Skyrme energy density formalism(SEDF)was used for this calculation.The SEDF uses the Hartree-Fock-Bogolyubov(HFB)computational program with Skyrme forces such as SkM*,SLy4,and SLy5 to obtain the nucleus-nucleus potential parameters for the above reactions.Using the SEDF model with SkM*,SLy4,and SLy5 interaction forces,the theoretical fusion cross-sections were determined above the barrier energy and compared with the available experimental fusion cross-sections.The results show a close agreement between the theoretical and experimental values for all selected systems at energies well above the barrier.However,near the barrier energies,the theoretical values were observed to be higher than the experimental values. | M.M.Hosamani A.Vinayak N.M.Badiger | 2020 | Nuclear Science and Techniques2020，31，9： | 0 |
