    "abstract": "We study the low-energy 3/2- and 1/2- states of He-5 and Li-5 in a\nmicroscopic cluster model. The scattering phase shifts of Bond (alpha+n) and of\nSchwandt (alpha+p), respectively, are reproduced well. We determine the\nresonance parameters by localizing the poles of the analytically continued\nS-matrix at complex energies. Our results differ from conventional R-matrix\nresonance parameters, which were extracted from experimental data using the\ndefinition of a resonance based on the positions and widths of reaction cross\nsection peaks. However, they nicely agree with the results of an extended\nR-matrix method which works at complex energies.",
