Strong coupling effects in proton scattering from 8He

Mackintosh, R. S. and Keeley, N. (2010). Strong coupling effects in proton scattering from 8He. Physical Review C, 81(3) pp. 1–15.



We present dynamic polarization potentials (DPPs), due to both neutron and neutron-pair pickup coupled reaction channels, contributing to the proton-nucleus interaction for the case of 8He at 15.66 MeV/nucleon, 25 MeV/nucleon and 61.3 MeV/nucleon. The available elastic scattering and transfer data were fitted in coupled reaction channels (CRC) calculations that allowed full inter-partition couplings. In addition, the contributions with various different combinations of coupled reaction channels were considered; we show that this can throw light on the non-locality of the underlying DPP, for which we determine the local and L-independent equivalent.
