摘要：

Data for the scattering of He-6, He-8, Li-9, and Li-11 from hydrogen are analyzed within a fully microscopic folding model of proton-nucleus scattering. Current data suggest that of these only Li-11 has a noticeable halo. For He-6, we have also analyzed the complementary reaction Li-6(gamma,pi(+))He-6(g.s). The available data for that reaction support the hypothesis that He-6 may not be a halo nucleus. However, those data are scarce and there is clearly a need for more to elicit the microscopic structure of He-6.
