Study of cross sections for (n,p) reactions on Hf, Ta and W isotopes

In the nuclear energy applications, hafnium, tantalum and tungsten are desirable materials in the production of super alloys for design of a nuclear power plant. In this study, cross sections calculations via TALYS-1.95, CEM03.01 and ALICE/ASH codes on 179Hf(n,p)179Lu, 180Hf(n,p)180Lu, 181Ta(n,p)181Hf, 182W(n,p)182Ta, 183W(n,p)183Ta, 184W(n,p)184Ta and 186W(n,p)186Ta reactions were carried out to determine the effects of various level density models and pre-equilibrium models on excitation functions. Besides, we presented our calculation results using the different empirical systematics at 14.5 MeV. The present results are also compared with the experimental and the evaluated nuclear cross section data from TENDL-2019 and JEFF-3.3.
