(n, p) Reaction Cross Sections Calculations of Some Stellar Iron Group Fusion Materials

The excitation functions for (n, p) reactions from reaction threshold to 24 MeV on some important iron (Fe) group target elements (20 ≤ Z ≤ 28) 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, 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 compound nucleus and pre-equilibrium reaction mechanism studied extensively. 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.
