✦ Synopsis

In a scintillation spectrometer the energy of y-rays is determined from the amplitude of the light pulses produced by the secondary electrons which are released in the scintillating material by the yrays i). However a monochromatic y-ray produces, in general, not de t Fig. 1. Primary Compton Distribution. do/de represents the electronic Compton cross section per recoil energy interval.

only electrons of the full energy --which give rise to the photo-peak in the spectrometer --, but also Compton-electrons with a continuous energy distribution between 0 < e -<< 272/(27 + 1); the number of primary processes with recoil energy e .... e + de is computed easily by means of the formula indicated in Fig. .
