摘要：

By a realistic dynamical microscopic reaction approach to He-5 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 not coherent though, unless the presently adopted alpha + n phase shift, extracted partly from alpha + p scattering data, is assumed to be incorrect. it is pointed out that the analog resonance in Li-5 behaves very differently because the shadow pole is located on another Riemann sheet.
