Analysis of Ge Detector Energy Spectra

Despite the superb energy resolution of Ge detectors compared to that of NaI(Tl) scintillators (see Fig. 12.32), analysis of complex gamma spectra is 

The energy assignment to the peaks of the spectrum is accomplished by calibrating the detector with a source that emits gammas of known energy and intensity. As explained in Sec. 9.10, calibration means to determine the con- 

For 2 MeV, the full-energy peak is intense and almost Gaussian in shape.

In spectra taken with thin Ge(Li) detectors, one may see the germanium escape peaks. The escape peaks (EP) have energy equal to
