Abstract : All cross sections were calculated for a natural mixture of isotopes. In addition to the total cross sections for inelastic collisions, measurements were made for Nb and Mo the inelasticscattering cross section with excitation of two groups of levels. The average excitation energies were found from the energy of inelastically scattered neutrons, which proved to be equal to 0.8 and 1.0 Mev for Nb and 0.8 and 1.1 Mev for Mo. A comparison of the results obtained with the data of other authors shows that with an over-all agreement, there are individual divergences. The greatest divergences are observed between the works based on the recording of neutrons and the works with gamma-rays. (Author)
