Using a time-of-flight spectrometer, the differential cross sections were measured for the elastic and inelastic scattering of 14.1 MeV neutrons by 6Li, 7Li, 9Be, 10B and 11B. In the case of elastic scattering by 7Li and 10B, correction was applied to subtract the contribution of in-elastic scattering from the unresolved first excited state, after which, the elastic scattering data were compared with predictions based on the optical model. The potential parameters derived with a seven-parameter search yielded angular distributions agreeing with the present experi-mental data. The expressions for these parameters are presented as a function of mass number.
The experimental data on inelastic scattering were analyzed with the distorted wave Born approximation. The deformation parameters were estimated to be nearly equal to or larger than unity for these nuclei.
