To obtain precise information about characteristics of gamma ray detector system responses, we developed new GUIcomputer program to analize full-energy absorption peak using our developed Delphi computer code for educational purpose. By use ofthe well known 4 nonlinear peak shaping functions, peaks were fitted with least square fit method in this code. In this paper, wedescribed the methods to search for 12 coefficients in above 4 nonlinear peak shaping functions by use of our developed code in details.The computer code was tested for 1 µCi 137Cs 661 keV gamma ray peak spectrum detected by 25 % relative efficiency HPGe detectorwith 5.35 cm (D)5.5 cm (L) size.
