Abstract

In the present work, the excitation functions of (n,2n) reactions for five isotopes of selenium (74,76,78,80,82Se) are calculated using ALICE/ASH, EMPIRE-3.2.2, PCROSS, and TALYS 1.6 computer codes based on statistical model up to 20 MeV. The theoretical calculations provide information of the (n,2n) excitation functions with the increasing target neutron number of selenium element. The calculated cross-sections were compared with experimental data from EXFOR and also with the crosssections estimated with semi empirical formula developed by Tet et al. (2008) [18]. Results show a reasonably good agreement between the calculations and the experimental data from literature.
