Parametrization of the coupled channels S matrix in the inelastic case: Relation to Arndt-Roper form

Parametrization of the coupled channels S matrix in the inelastic case: Relation to Arndt-Roper form

A previously introduced parametrization of the S matrix for two coupled channels is extended to allow use of Blatt-Biedenharn type phase shifts. It is then shown how the K-matrix parametrization of Arndt and Roper is related to the other schemes.
