摘要：

Measurements are described of the Compton suppression of two prototype detectors for GAMMASPHERE. The prototypes consist of a large (75% efficient) n-type germanium detector with a BGO Compton-suppression shield. A peak-to-total ratio of 0.678(2) is achieved with a Co-60 source. This is the best ratio reported to date for a detector of this kind. The results are compared with those obtained from Monte Carlo simulations. The simulations can predict the observed peak-to-total ratios if a significant background from scattered photons is included.
