For moderately large organic scintillators, a linear relation is found between the position of the gamma -ray Compton peak and the maximum energy transfer in a flrst Compton collision. Extrapolation yields a positive intercept on the energy axis, as a result of the dependence of the specific light output of scintillators on the linear energy transfer of charged particles. The broadening of the Compton peak on the highenergy side has statistical components, intrinsic line broadening components arising from multiple interactions of the gamma -ray, and geometrical components resulting from the variation of light collection efficiency with the position of the event in the scintillator. The dependence of these three components on gamma -ray energy is considered and their approximate magnitudes for two plastic scintillator units are calculated from experimental gamma -ray spectra.
