In the present study, we reexamine quasi-elastic scattering of 7 Li by 120 Sn at incident energies E Lab = 19.5, 20.5, and 25.0 MeV. The theoretical results are obtained by using both a phenomenological model and double-folding model (DFM) within the framework of an optical model. We also investigate the role of the surface potential, which is connected to direct reactions. The agreement between the phenomenological model and the DFM is shown in comparison to each other in connection with the experimental data. This comparison provides information about the similarities and the differences between the models used during the calculations.
In this paper, our purpose is to calculate photon-matter interaction parameters of Ni-based alloys, Inconel-617 and Incoloy-800HT, which are the main candidates for high-temperature applications such as spacecraft, gas turbines, nuclear reactors and rocket motors. The radiation attenuation parameters and buildup factors were obtained in a wide energy range by using Phy-X/PSD and EpiXS softwares to determine the radiation protection capabilities of the alloys. Fast neutron removal cross sections of the alloys were also calculated. It was observed that Inconel-617 has higher shielding ability than Incoloy-800HT. The shielding potentials of the alloys were compared with those of other shielding materials (ordinary concrete, hematite-serpenite, ilmenite-limonite, steelscrap, basalt-magnetite, steel-magnetite and ilmenite concretes) reported before, and it was concluded that Inconel-617 and Incoloy-800HT have more shielding ability than those.
