Abstract

The p–⁶He potential has been determined by inverting the S-matrix, calculated from single-channel RGM without absorption, over the energy range E_c.m.=0.5,1.0,…,25 MeV. Energy-dependent IP inversion was used, but with energy-independent spin–orbit terms. A potential with odd- and even-parity components reproduces S_lj(E) from l=0 to l=4 over the whole energy range. The central components of the potential have a smooth, predominantly linear, energy dependence that is consistent with global phenomenology. We compare the similar neutron–⁶Li (IAS) interaction. Various features in the potentials deserve explanation. The procedure employed here could extract dynamic polarization potentials for the p–⁶He interaction from S_lj(E) from multichannel RGM calculations, should these become available.
