On correctness of some processing operations for two-step cascade intensities data from the (n,2gamma) reaction

An influence of some incorrectness of analysis on the level densities and radiative strength functions derived from the experimental gamma-spectra is considered. It was shown that the obtaining of reliable data from the reaction (n,2gamma) requires one to derive dependence of the two-step cascade intensities on their primary transitions energy. The influence of some conditions of an analysis of the experimental gamma-spectra from reaction (3He,alpha) on the expected value of both level density and radiative strength functions was estimated. The ways to decrease these uncertainties are suggested.
