Experimental and theoretical studies of (n, p) reactions on Ge isotopes

Abstract

Systematic experimental and theoretical investigations of the 70,72,73,74Ge(n,p)70,72,73,74Ga reaction cross-sections are presented in the energy range from threshold to about 17MeV neutron energy. The 72,73Ge(n,p)72,73Ga reaction cross-sections were measured from 8.8 to 11.4MeV by using the activation method, relative to the 27Al(n,α)24Na reference reaction. The quasi-monoenergetic neutron beams were produced via the 2H(d,n)3He reaction at the 5MV Van de Graaff (VdG) Tandem T11/25 accelerator of NCSR “Demokritos”. Statistical model calculations using the code EMPIRE (version 2.19) and taking into account pre-equilibrium emission were performed on the data measured in this work as well as on data reported in the literature.
