Determination of the effects of nuclear level density parameters on photofission cross sections of ²³⁵U up to 20 MeV

Abstract

Abstract. The level density models and level density parameters are two of important quantities for describing the properties of nuclei. Especially, the level density parameter has an important role as input in calculation of reaction cross sections. In this study, the cross sections on 235 U(g,f) reaction were calculated for different level density models using the TALYS 1.6 code up to 20 MeV gamma incident energies. First, it was determined the level density model that was the closest to the experimental data. Secondly, cross sections obtained for different level density parameters of this model were compared with experimental data from the EXFOR database. Thus it was determined the best level density parameter fit to experimental data.

Investigation of Neutron-Induced Reaction Cross Sections for Several Nuclear Reactor Structural Materials

“…Calculating neutron-induced reaction cross sections of Zr-Fe-Cr-Sn-Nb element therefore gives some insight into the suite of alloys that used in the structural and provides a degree of information regarding the role of insulation and resistance of zirconium alloy to the harmful effects of radiation. For that purpose, previously studies for calculation of the cross sections of the various interested reaction are done with help of available codes such as TALYS, EMPIRE, ALICE which include theoretical models developed by the combination of exist theoretical knowledge and previously obtained outcomes of the experiments [4][5][6][7].…”
