The p+He-6 interaction from E-cm=0.5 to 25 MeV

摘要

The p-He-6 potential has been determined by inverting the S-matrix, calculated from singlechannel 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 1 = 0 to 1 = 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-Li-6 (IAS) interaction. Various features in the potentials deserve explanation. The procedure employed here could extract dynamic polarization potentials for the p-He-6 interaction from S-lj(E) from multichannel RGM calculations, should these become available.
