Parametrization of the coupled channelsSmatrix in the inelastic case: Relation to Arndt-Roper form
Donald W. L. Sprung · Physical Review C · 1987
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.
