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

Systematic experimental and theoretical investigations of the Ge-70,Ge-72,Ge-73,Ge-74(n, P)(70,72,73,74) Ga reaction cross-sections are presented in the energy range from threshold to about 17 MeV neutron energy. The Ge-72,Ge-73(n, P)(72,73) Ga reaction cross-sections were measured from 8.8 to 11.4 MeV by using the activation method, relative to the 27Al(n, alpha)Na-24 reference reaction. The quasi-monoenergetic neutron beams were produced via the H-2(d, n)He-3 reaction at the 5 MV 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.
