Abstract :
High-purity germanium detectors containing differing concentrations of [H2], [Si] and [O2] have been irradiated with fast neutrons from a 238Pu 9Be source (average energy 4.2 MeV). Measurements of the full width at half maximum (FWHM) resolution of the 1.17 MeV 60Co photopeak have been carried out as a function of neutron flux, electric field, time after application of bias and detector thickness.
