摘要
Published data on resolution degradation of high-purity germanium (HPGe) detectors after irradiation with fast neutrons are reviewed, and the possible role of point defects is quantified. Resolution degradation is between one and two orders of magnitude too severe to be attributed to the point defects present. Disordered regions must dominate resolution degradation until the detector has been sufficiently annealed that the pre-irradiation resolution is almost recovered. In capacitance spectroscopy the corresponding emission from these disordered regions has presented problems either in identification or interpretation.
