✦ Synopsis
e prsscnt a definition for the absolute eigenphase sum for multichannel quantum-mechanical scati:;ing problems. The absolute eig,enphase sum is useful for finding resonances. especially very narrow and hard-to-locate ones, for which the savings in computer time can be very lzzge_ We have demonstrated the pmcticzdity of the method by implemenrin~ it lo lo~zre a resonance in the diabatic representation with the Numcrov method and in the adiabatic representation with R-matrix propagation. Resonances in quantum-mechanical coupled-chan-
