Description
A numerical method is developed to search the complex momentum plane for the poles of the multichannel T matrix. No resonance or continuum wave functions are calculated and no complex basis functions are required. The appropriate Green's function is constructed and used to enforce the asymptotic behavior. Results are obtained for a three-state model problem and compared with results from other techniques
