Cross section of reaction ¹⁸¹ Ta(p,nγ) ¹⁸¹ W and the influence of the spin cut-off parameter on the cross section

Abstract

In this work, the program Cindy was modified to calculate the formation cross section of each energy level of residual nucleus 181W resulting from the reaction 181Ta(p,nγ) 181W. The concerned cross sections calculated at proton energy Ep = 4.5–8.5 MeV agreed well with experimental results. The influence of the spin cut-off parameter in the energy level density model on the cross section was studied. The obtained results show that the influence of spin cut-off is obvious for lower energy levels.
