Abstract

By a realistic dynamical microscopic reaction approach to He5 we reproduce the empirical positions of the two S matrix poles associated with the 3/2+ resonance, and unambiguously prove that it arises from the t+d channel. The picture is not coherent though, unless the presently adopted +n phase shift, extracted partly from +p scattering data, is assumed to be incorrect. It is pointed out that the analog resonance in Li5 behaves very differently because the shadow pole is located on another Riemann sheet.
