Summary
High-precision neutron capture data on 76Ge are of interest for fundamental research in nuclear astrophysics and for lowbackground experiments in the search of neutrinoless double β decay. This work presents neutron capture resonance data obtained at the n_TOF facility, providing for the first time information on individual resonance parameters relevant for radiative neutron capture on 76Ge up to 52 keV. These resonance data were used to constrain average resonance parameters and Maxwellian averaged cross sections. Capture events were detected by measuring the prompt capture γ rays with four deuterated benzene (C6D6) liquid scintillators These detectors have been optimized for an extremely low sensitivity to scattered neutrons [24,25].
