Scientific paper

When 1 - 10 MeV neutrons scatter inelastically in germanium detectors, they will excite an 847.2 keV gamma-ray transition in 76Ge. The flux-equivalent strength of this line is estimated to be 0.5 - 5.0×10-4cm-2s-1 in germanium detectors flown at the top of the atmosphere. At this level, the background line can interfere with gamma-ray observations of supernovae.
