    "abstract": "A new type of supersymmetric transformations of the coupled-channel radial\nSchroedinger equation is introduced, which do not conserve the vanishing\nbehavior of solutions at the origin. Contrary to usual transformations, these\n``non-conservative\u0027\u0027 transformations allow, in the presence of thresholds, the\nconstruction of potentials with coupled scattering matrices from uncoupled\npotentials. As an example, an exactly-solvable potential matrix is obtained\nwhich provides a very simple model of Feshbach-resonance phenomenon.",
