A universal method of spectrum analysis

To solve the problem of the apparatus decomposition in a way most independent of the subjectivity in describing the shapes of the spectrum components, both those of the useful ones and that of the background, a method is proposed, which uses as models the really measured histograms of the isolated spectrum components, introducing in them some fundamental geometric characteristics of the functions as parameters. The method is applicable to the analysis of a very large class of apparatus spectra. The algorithm aspect of the method is described in detail. (Auth.)
