Measurement of the 76 Ge ( n , γ ) cross section at the n_TOF facility at CERN

Abstract

The 76 Ge ( n , γ ) reaction has been measured at the n_TOF facility at CERN via the time-of-flight technique. Neutron capture cross sections on 76 Ge are of interest to a variety of low-background experiments, such as neutrinoless double β decay searches, and to nuclear astrophysics. We have determined resonance capture kernels up to 52 keV neutron energy and used the new data to calculate Maxwellian-averaged neutron capture cross sections for k B T values of 5 to 100 keV.
