Abstract: A pulse processing technique has been developed which improves the gamma-ray energy resolution of mercuric iodide detectors. The technique employs a fast (100 ns) and a slow (6.4 microsec) pulse height analysis to correct for signal variations due to variations in charge trapping. The capabilities of the technique for energy resolution enhancement are discussed as well as the utility of the technique for examining the trapping characteristics of individual detectors. An energy resolution of 2.6 percent FWHM at 662 keV was achieved with an acceptance efficiency of 100 percent from a mercuric iodide detector which gives 8.3 percent FWHM using standard techniques.
