Abstract
Time delay in collisions is analyzed when zero-angular-momentum resonances are present. It is shown that very large delay comes from an orbiting wave. This is reflected in rapid change with energy of the phase of the -matrix residue. In addition, we show the proper definition of time delay in terms of the scattering amplitude.
