A solution to the pulse pileup and peak shape distortion problem

The pileup loss from the peak area and peak shape distortion effects are of considerable importance in routine activation analysis where the count rate may vary considerably from one sample to another. In this paper simple linear approximations for the peak shape change and efficiency loss have been used to show that correct results to within 2% are obtainable in the range 1000 cps to 10 000 cps.
