Abstract
The cross-section (excitation functions) of neutron and proton threshold reactions has gained considerable importance for the production of Therapeutic radioisotopes in the present era. The present study based on TALYS 1.6 code to calculate the cross section theoretically. This code has been used to evaluate (n,p) & (p,n)reaction crosssections for the production of therapeutic radioisotopes (64Cu, 64Ni, 67Cu, 89Sr, 90Y, 124I, 125I, 153Sm, 169Y, 186Re, 192Ir) for which a very few experimental data are available in EXFOR but some are discrepant. These theoretical calculations have been performed within the frame work of the level density parameter with pre-equilibrium effects using
recent TALYS 1.6 code from the energy range threshold to 20 MeV. Before running the code optimization of input parameter (level density formulation) has also been done. The obtained results have been compared with EXFOR data and various available data files (ENDF, IAEA and TENDL) along with the experimental data available in the literature. It is concluded that computed results using TALYS 1.6 code is compatible
with the experimental data from the literature.
