Abstract

In this study neutron production cross sections of 197Au have been calculated using equilibrium and pre-equilibrium nuclear reaction models. While Weisskopf-Ewing model has been used for the equilibrium process in the calculations, two component exciton, hybrid and geometry dependent hybrid nuclear reaction models have been used for the pre-equilibrium process. For Weisskopf-Ewing, Hybrid and Geometry Dependent Hybrid Model calculations ALICE/ASH, for two component exciton model calculations TALYS 1.2 codes have been used. The calculated results have been discussed and compared with the experimental data
