Abstract
We apply two-step phenomenology (S(l) fit then inversion) to establish local potentials fitting the elastic scattering of Li-11 from Si-28 a t 319 MeV lab energy and Li-11 from C-12 at 637 MeV lab energy. We rea dily find potentials giving goad fits. Despite severe ambiguity proble ms, a consistent picture emerges which in essential features is common to both cases. Potentials are found which entail a much longer tail o n the real component than is predicted by folding models which incorpo rate current models of halo structure. We suggest a picture of Li-11 s cattering in which the two outer neutrons contribute to a long tail in the real part of the potential, but not in the imaginary part.
