Abstract
The simple method of transforming the computed energy function of the displacement cross section into the damage function is proposed. The method is based on experimental results on the irradiation of samples in two reactor fields with strongly different neutron spectra. The damage cross section can be represented as σdam(E) = σdis(E)f(E), where f(E)=a0(E/10)a1is a correction function. The normalizing factor a0 is determined experimentally. The parameter a1 is determined from the equality of the ratios of the radiation-induced changes in the properties and neutron fluences with energy above the threshold EL. The dependence of a1 on EL is calculated beforehand. 3 tables, 7 references.
