Abstract
This Letter presents the first application of the Schwinger variational principle for multichannel scattering. Results are presented for an exactly soluble two-channel model problem. The accuracy and convergence of the Schwinger variational principle are shown to be extremely good and superior to those of other variational methods.Keywords
