Abstract

The polarization and the differential scattering cross sections for neutrons scattered from Be9 were measured at 5 angles for neutron energies from 0.2 to 2.0 MeV. The data are interpreted in terms of a two-channel process. The neutron scattering resonances at 0.625 and 0.815 MeV, corresponding to levels in Be10 at 7.37 and 7.54 MeV, were assigned the spin and parity values Jπ=3 (l=2) and Jπ=2+ (l=1), respectively. The calculations took account of the effects of s-wave and p-wave backgrounds as well as approximate contributions of 1 and 2 bound states.
