Measurements of (n,x) nuclear reaction cross sections for Ge isotopes

Neutron cross sections were measured for Ge isotopes by the neutron activation method. Foils of natural germanium were irradiated with 14.5 MeV neutrons produced by a neutron generator NG-300/15. To ensure results accuracy and precision, coincidence summing and self-absorption effects have been taken into account. Calculations of corrections have been performed with Monte Carlo simulations. The determination of the Ge-72(n, 2n) Ge-71 cross section is reported for the first time. Theoretical calculations of cross sections were performed with the Talys-0.64 code.
