摘要：
The Studsvik high-resolution, low-background time-of-flight facility has been used to measure differential neutron-scattering cross sections for 9Be, 14N and 16O at the neutron energy 21.6 MeV. Angular distributions in the range 10°-160° have been measured for elastic scattering, and also for inelastic scattering from some low-lying levels in the three nuclei. The results for elastic scattering have been treated in terms of a phenomenological spherical optical model, while inelastic-scattering cross sections for 14N and 16O were calculated using the distorted-wave Born approximation. The coupled-channels formalism for rotational and vibrational nuclei was also used in the analysis of scattering from 9Be and 16O, respectively. Potential parameters and deformations from these calculations are given in the paper. © 1990.
