To check the inelastic neutron scattering cross sections previously measured, the entire experiment was repeated by use of neutron time-of-flight techniques. In particular, the neutron inelastic scattering cross sections were measured for the following elements with an incident neutron energy of 15 MeV: (1) at 90 deg. for Be, B10, B, C, Mg, Si, Mn, Fe, Co, Ni, Cu, Se, Mo, Cd, W, Pb, Ce, Sb, V, Y and Ti; (2) at scattering angles of 30, 40, 55, 70, 90, and 125 deg. for Be, Co, Mo, Cd and W.A computer code MULTSCAT was developed to obtain the corrections due to multiple scattering of neutrons in the scatterer. This code was compiled in Fortran-63 language for a CDC-1604 computer. The experimental cross sections obtained in the present project were corrected for double scattering by means of the MULTSCAT code. (Author).

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).
