  Predictions of cross sections and analyzing powers using g-folding optical
potentials for the scattering of 71A MeV 6,8He ions from (polarized) hydrogen
are compared with data. A g-folding model in which exchange amplitudes are
evaluated explicitly was used with wave functions of 6,8He specified from a
no-core shell model that used a complete (0+2+4)hw basis. The analyzing powers
reveal some sensitivities to the details of the wave functions, especially in
the case of halo nuclei.
