Description

The response function and the rejection factor of Compton suppression gamma spectrometers have been calculated using the Monte Carlo method starting from low energy region (20 keV). Special emphasis has been given to the influence of inactive layers surrounding the Ge detector on the Compton suppression factor. The calculated properties of two types of Compton suppression detectors have been compared with experimental data. Some possible modifications of Compton suppression spectrometer intended for the study of low gamma energy region are suggested. 12 refs.; 6 figs.; 2 tabs
