On the basis of the character of Ge (Li) gamma-full-energy-peaks obtained from a multichannel analyzer

minicomputer can be used to analyse gamma-spectrum. The bands of exploration are applied to the automatic peak search. Peak area and position are determined by peak criteria. After energy calibraton

the following can be calculated: peaks energy

absolute detection efficiency of full-energy peak in a certain geometry

absolute activity of γ-peak and so on. Some examples are given and the advantages and disadvantages have been discussed.
