Query: Antisymmetry and channel coupling contributions to the absorption for p
  + alpha/d + 3He   To understand recently established empirical p + alpha potentials, RGM
calculations followed by inversion are made to study contributions of the d +
3He reaction channels and deuteron distortion effects to the p + alpha
potential. An equivalent study of the d + 3He potential is also presented. The
contributions of exchange non-locality to the absorption are simulated by
including an phenomenological imaginary potential in the RGM. These effects
alone strongly influence the shape of the imaginary potentials for both p +
alpha and d + 3He. The potentials local-equivalent to the fully
antisymmetrised-coupled channels calculations have a significant
parity-dependence in both real and imaginary components, which for p + alpha is
qualitatively similar to that found empirically. The effects on the potentials
of the further inclusion of deuteron distortion are also presented. The
inclusion of a spin-orbit term in the RGM, adds additional terms to the
phase-equivalent potential, most notably the comparatively large imaginary
spin-orbit term found empirically.
