Predictions of cross sections and analyzing powers using $g$-folding optical potentials for the scattering of $71A$ MeV ${}^{6,8}$He 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 ${}^{6,8}$He specified from a no-core shell model that used a complete $(0+2+4)\hslash \omega$ basis. The analyzing powers reveal some sensitivities to the details of the wave functions, especially in the case of halo nuclei.
