Excitation Function of (n,α) Reactions of Hafnium and Tungsten Isotopes for Fusion Reactor Technology

Abstract

The cross-section of 176Hf(n,α)173Yb, 177Hf(n,α)174Yb, 178Hf(n,α)175Yb, 179Hf(n,α)176Yb, 180Hf(n,α)177Yb, 182W(n,α)179Hf, 183W(n,α)180Hf, 184W(n,α)181Hf and 186W(n,α)183Hf reactions have been analyzed by using TALYS 1.4 in the energy range between 13 and 15 MeV. The result has been compared with several experimental values taken from EXFOR data library and evaluated data file of ENDF/B-VII.0 and ENDF/B-VII.I. It is concluded that the present results contribute significantly to enhance the knowledge of cross-sections and in optimizing the input parameters required in model based evaluation.
