Total and isomeric-state cross sections for the Ge 76 (n,2n) Ge 75 reaction from threshold to 14.8 MeV
© 2017 American Physical Society. The cross sections for the reaction Ge76(n,2n)Ge75 to both the isomeric state and the ground state of Ge75 have been measured with the activation method between 10 and 15 MeV in small energy steps to help resolve inconsistencies in the existing database. The Au197(n,2n)Au196 reaction with its known cross section was used for normalization of the data, which are compared to experimental and evaluated data of the EXFOR, EAF, JENDL, ENDF, and TENDL libraries. Model calculations using the talys-1.8 code are presented which also allow for the extrapolation to higher neutron energies. The data are important to estimate potential neutron-induced backgrounds in currently running large-scale experiments aimed at the discovery of neutrinoless ββ decay of Ge76.
