Abstract：
A complete automatic program for fission products Ge(Li) Gamma-ray spectraanalysis-GSAP is presented. The computational methods of the program are brieflydescribed. A modified Levenberg algorithm with suitable argument constraints isused to solve the least-square peak fitting problem. 8 overlapping peaks can be an-alysed by this program. An unsymmetrical Gaussian superimposed on a parabolicbackground is selected as the fitting function which usually gives a good fit to mostof the peaks in a spectrum. Various experimental tests are described for proving thereliability and accuracy of the program. Satisfactory results for fission yield measu-rements have been obtained with this program. In fact, this program is a general-purpose program, which can be applied to analyse the Ge (Li) Gamma-ray spectrafrom other kinds of experiments.
