Abstract

The dynamic polarization potential contribution to the effective interaction between 6He and 208Pb at 27 MeV, due to breakup channels, is recalculated exploiting a recently developed improved model for 6He. The most general features of the long-range attractive and absorptive components remain the same as were found in an earlier study, but the asymptotic magnitudes are reduced by factors of about 2.5 and 4.5, respectively. We draw conclusions from these results, as well as from further calculations at 22 MeV, closer to the Coulomb barrier, and at 32 MeV.
