Chance coincidence losses in a Compton suppression spectrometer are in
strumentally corrected by comparing the chance coincidence rate to the
counting rate of the Germanium detector. The normally not observable
chance coincidence rate is reconstructed from the rates of Germanium d
etector and scintillation detector in any auxiliary coincidence unit,
after the destruction of true coincidence by sufficiently delaying one
of the coincidence partners. (C) 1998 Elsevier Science B.V. All right
