Abstract

Microscopic coupled-channels calculations for the ground-state rotational band of Be9 are performed using the folding model and density-dependent effective interactions. Transition densities are obtained either from the shell model or from fits to electron scattering data. The quadrupole contribution to elastic scattering enhances the cross section and damps the analyzing power for momentum transfers larger than about 1.2 fm1. Channel coupling is more important for the 7/2 than for the 5/2 state and roughly follows the energy dependence of the interaction strength. Comparisons are made between calculations using either theoretical effective interactions or empirical effective interactions previously fitted to data for O16 or Ca40. The results demonstrate that medium modifications are quite important and well described by the local density approximation. Therefore, the effective interaction depends primarily upon local density and is almost independent of nucleus, state, or deformation.
