Abstract

The excitation functions for (n,p) reactions from reaction threshold to 24 MeV on some important iron (Fe) group target elements for astrophysical (n, p) reactions such as Si, Ca, Sc, Ti, Cr, Fe, Co and Ni were calculated using TALYS-1.0 nuclear model code. The new calculations on the excitation functions Of 28Si(n,p)28Al, 29Si(n, p)29Al, 42Ca(n, p)42K, 45Sc(n, p)45Ca, 46Ti(n,p)46Sc, 52Cr(n, p)52V, 53Cr(n, p)53V, 54Fe(n,p)54Mn, 57Fe(n,p)57Mn, 59Co(n, p)59Fe, 58Ni(n, p)58Co and 60Ni(n, p)60Co reactions have been carried out up to 24 MeV incident neutron energy. In these calculations, the pre-equilibrium and equilibrium effects have been investigated. Statistical model calculations, based on the Hauser-Feshbach formalism, have been carried out using the TALYS-1.0 and were compared with existing experimental data as well as with evaluated data files (Experimental Nuclear Reaction Data (EXFOR).According to these calculations, we assume that these model calculations can be applied to some heavy elements, ejected into interstellar medium by dramatic supernova events.
