Abstract

The (p,n) reaction in 7Li at 94 MeV is studied in the impulse approximation. The differential cross sections for exciting the isobaric analogue state and the 0.431 MeV state in 7Be are obtained using LS-coupled shell-model wave functions. Fairly good shape agreement with the available experimental results is obtained. These results are discussed, together with the inelastic proton scattering to the 0.478 MeV state in 7Li, as a mode of investigating the model wave functions used; where the small-angle results as predicted by the theory appear to be in conflict with the experimental data. Need for more experimental data at small angles for these reactions is stressed.
