摘要

The Ge-76(n,p)Ga-76 reaction and the subsequent beta decay of Ga-76 to Ge-76 has been used to excite the 3951.89-keV state of Ge-76, which decays by the emission of a 2040.70-keV gamma ray. Using high-purity germanium detectors, the associated pulse-height signal may be undistinguishable from the potential signal produced in neutrinoless double-beta decay of Ge-76 with its Q value of 2039.0 keV. At 20-MeV neutron energy the production cross section of the 2040.70-keV gamma ray is approximately 0.1 mb.
