Estimate of the cross section for thermal neutrons
Yu. Petrov, V. Yu. Petrov B. P. Konstantinov Petersburg Nuclear Physics Institute, Russian Academy of Sciences
Аннотация:
Cross section of the thermal neutrons in the framework of
statistical approach to the complicated nuclei is considered. We calculate
probability distribution $\mathcal P(z)$ to have given cross section $\sigma$
(determined by fluctuations of resonance positions and widths). $z$ is the
ratio of $\sigma$ to $\sigma^*$ where $\sigma^*$ is the cross section for the
model of equidistant resonances with same width. The last quantity can be
presented in terms of neutron strength function for given nuclei. Probability
distribution $\mathcal P(z)$ is universal for all nuclei.
