Evaluation of cosmogenic Ge-68 background in a high purity germanium detector via a time series fitting method

W. H. Dai, J. K. Chen, H. Ma +4

Ge-68 is a cosmogenic isotope in germanium with a half-life of 270.9 days.Ge-68 and its decay daughter Ga-68 contribute considerable background with energy up to 3 MeV to low backg…
