The cross-sections for the interaction of protons with isotopes of elements from C to Cu were obtained at energies from the reaction threshold to 200 MeV. The work included calculations using different models and computer codes, ALICE, CEM, PHITS, and TAYLS, analysis of experimental data, and evaluation of cross sections.
All types of experimental data were applied to correct calculated...
The focus of this research work is to determine experimentally the ground state reaction rates for eight photoneutron reactions proposed to be investigated via photon-induced activation at the Madison Accelerator Laboratory (MAL), a unique bremsstrahlung facility on the campus of James Madison University, in Harrisonburg, Virginia. The eight photoneutron reactions are – 64Zn(γ,n), 70Ge(γ,n),...
Accurate modeling of neutron induced capture γ-ray production is essential for many applications such as understanding γ-ray heating in critical systems, shielding calculations, nuclear medicine, particle physics experiments and active neutron interrogation. To determine the accuracy of nuclear data evaluations and simulation tools used to transport thermal neutron capture γ-ray cascades, the...
Photonuclear reaction data are important for a variety of applications, from isotope production for medicine to radiation shielding to understanding astrophysical nucleosynthesis. Yet cross sections of photonuclear reactions for many species are not well known. Of the 286 combined stable and primordially stable (t1/2 > 7 x 108 yr) isotopes that exist, only a small fraction (approx. 10%) of the...
The material displacement damage index of displacement per atom (dpa) is obtained by the particle flux and the displacement cross section. However, the experimental data of the displacement cross section was scarce, so our group conducted the measurement using proton beams. So far, the experimental data of protons up to 30 GeV were obtained using FFAG at Kyoto University, RCNP at Osaka...
