74 Ge(n, γ) cross section below 70 keV measured at n_TOF CERN
(Springer Nature, 2022)
Neutron capture reaction cross sections on 74Ge are of importance to determine 74Ge production during the astrophysical slow neutron capture process. We present new resonance data on 74Ge(n, γ) reactions below 70 keV neutron ...
