Excitation functions of the individual levels of the nuclei U235, U233, and Pu239, including competition between inelastic neutron scattering and fission of the nuclei

N. Bohr's statistical theory [1, 2] has been used to calculate the excitation functions for inelastic scattering of neutrons at the individual levels of the target nuclei U²³⁸, U²³³, and Pu²³⁹ including competition between inelastic scattering and fission. The fission width was found from N. Bohr and Wheller's formula [3] including the penetrability of the fission barrier as given by Hill and Wheller [4]. The fission thresholds and the number of transition states at the saddle point were taken both from the experimental data of [5], and the theoretical data of [6].In conclusion the authors express their gratitude to L. N. Usachev, V. S. Stavinskii, and N. S. Rabotnov for their valuable comments and discussions as well as to L. S. Anufrienko for doing the calculational work.
