A sophisticated photomultiplier response function was suggested for single
photoelectron analysis of the compact metal package photomultiplier spectra
. The spectra taken by Hamamatsu R5600 photomultipliers have been analysed
by the presented method. The detailed analysis shows that the method approp
riately describes the process of charge multiplication in these photomultip
liers and can be used to find their basic internal parameters. (C) 2001 Els
