Broad resonances of H
−
and Ps
−
obtained by complex-rotation methods are treated with hyperspherical
calculations. The resonances are identified as a peak in the energy dependence of time delay
obtained in the single-channel calculation using a hyperspherical adiabatic potential curve. The peak occurs
even when the adiabatic potential is purely repulsive, because the effective potential (the sum of adiabatic
potential and adiabatic correction) is attractive relative to the potential represented by its asymptotic
form. -
