Abstract

The projectile breakup effect on th elastic and inelastic scattering of ^9Be has been studied by coupled-channel calculations based on the microscopic cluster-model wave functions for ^9Be. All the diagonal and coupling potentials are calculated by doubly folding the M3Y effective nucleon-nucleon interaction with the diagonal or transition densities of projectile and target nuclei. It is found that the effect is quite significant and essential to understand the elastic and inelastic scattering. The dynamical polarization potential clearly shows the repulsive nature of the breakup effect. The calculation also reproduces the observed cross section for the sequential-breakup process vir 5/2^- resonance state of ^9Be.
