Abstract

We present dynamic polarization potentials (DPPs) arising from neutron pickup coupled reaction channels, contributing to the proton-nucleus interaction for 71 MeV/nucleon protons scattering from ⁶He. The DPPs do not represent a uniform renormalization of the potential and result in a change in the rms radius of the real part. The inclusion of breakup of the deuteron somewhat reduces the repulsive effect of the coupling and enhances the absorption. The linearity of the coupling effect suggests a method of incorporating it into a computationally feasible phenomenological scheme.
