  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.
