photoelectric peak

Synonym: photopeak

Of a spectrum of γ-radiation, the part of the spectral response curve corresponding to the absorption in the radiation detector by the photoelectrical effect of the detected γ-energy. In most cases the peak also contains events caused by multiple processes and use of the expression total absorption peak or full energy peak is to be preferred. Synonymous with photopeak.
