Abstrakt

Neutron capture reaction cross sections on $$^{74}$$Ge are of importance to determine $$^{74}$$Ge production during the astrophysical slow neutron capture process. We present new resonance data on $$^{74}$$Ge($$n,\gamma $$) reactions below 70 keV neutron energy. We calculate Maxwellian averaged cross sections, combining our data below 70 keV with evaluated cross sections at higher neutron energies. Our stellar cross sections are in agreement with a previous activation measurement performed at Forschungszentrum Karlsruhe by Marganiec et al., once their data has been re-normalised to account for an update in the reference cross section used in that experiment.
