We study the low-energy [Formula Presented] and [Formula Presented] states of [Formula Presented]He and [Formula Presented]Li in a microscopic cluster model. The scattering phase shifts of Bond [Formula Presented] and of Schwandt [Formula Presented], respectively, are well reproduced. We determine the resonance parameters by localizing the poles of the analytically continued [Formula Presented] matrix at complex energies. Our results differ from conventional [Formula Presented]-matrix resonance parameters, that were extracted from experimental data using the definition of a resonance based on the positions and widths of reaction cross section peaks. However, they nicely agree with the results of an extended [Formula Presented]-matrix method that works at complex energies.
