✦ Synopsis

An analytic continuation method for obtaining resonance widths from real eigenvalues in stabilization graphs has been extended to the case of multiple decay channels. An approximate procedure for decoupling the exit channels permits calculation of partial widths in reasonable agreement with exact values, especially for narrow resonances. Results are reported for a simple model scattering system introduced by Fels and Hazi.
