Abstract

The dynamic polarization potential (DPP) contribution to the effective proton-nucleus interaction, that is due to the coupling of deuteron channels, is evaluated by applying SljV(r) inversion to the elastic channel S-matrix from coupled reaction channel calculations of proton elastic scattering. This was done for protons scattering from 10Be at 12, 13, 14, 15, and 16 MeV; nonorthogonality corrections were included. We find a consistent pattern of a repulsive real and an absorptive imaginary DPP, with the absorption shifted to a larger radius. This is consistent with what has been found for proton scattering from the neutron skin nucleus 8He. The DPP is not of a form that can be represented by a renormalization of the bare potential, and has properties suggesting an underlying nonlocal process. We conclude that deuteron channels cannot be omitted from a full theoretical description of the proton-nucleus interaction (optical potential).
