AbstractAbstract
[en] The influence of the (n,γf) process on the calculation of energy dependences of average widths, radiation capture sigmasub(γ) and fission sigmasub(F) cross sections is analyzed. The calculations have been made using a statistic model on the example of a 239Pu nucleus. Presented are 239Pu radiation widths, calculated with and without account of (n,γf) processes with various spectral factor presentations for 0.1 keV neutrons. The calculation of (n,γf) processes brings about a change of the energy dependence of the average radiation widths and sigmasub(γ). The results of calculations show, that preferable is the f(E,epsilonγ) spectral factor presentation in the form of a lorentz dependence
