A Factorization of the S-Matrix into Jost Matrices
Abstract
An effective algebraic approach to S--matrix factorization into Jost matrices is developed in the case of coupled channels. The Jost matrix is given as a solution of boundary value Riemann -- Hilbert problem. A rational form is assumed for tangent of mixing angle, while there is no limitations for approximation of phase shifts.
