Twelve monoenergetic gamma-ray-sources are used to obtain the response function for a 3 in. x 3 in. NaI crystal in the energy range 0.1 to 2.0 Mev. The analyzing program searches for groups of photo-peaks. They are fitted by sums of Gaussians, deciding their number by the statistical F-Test. Identified photo-peaks and the corresponding compton distributions are subtracted from the measured pulse-height spectrum, starting at high energies. A number of known spectra were analyzed in order to check the reliability of the procedure depending on counting rate, number of gamma-rays in a group, and their relative intensitie and the number of subtractions. The results are discussed. (auth)
