Abstract: In the program of processing of -spectra "GAMMAPEAKS" the algorithm of automatic search of peaks in -spectra based on use of convolution of sites of a spectrum from a negative smoothed second derivative of gaussian is developed.In the new version of this program before creation of a search spectrum the convolution of an initial spectrum with an ideal gaussian of small amplitude and variance was carried out.As a result of this convolution the initial spectrum on sites with "poor" statistics was well smoothed that facilitated search of peaks on a search spectrum.The search spectrum was under construction by convolution of the received -spectrum from the negative smoothed second derivative of gaussian that looks like a step.The search result of peaks shows that the "GAMMAPEAKS" program marks peaks more precisely, than the previous versions of this program in which were not used formulas based on Student's test.
