    "abstract": "I present ongoing developments on hybrid models which combine the potential\nmodel, for the description of the background, with the R-matrix model, for the\ndescription of discrete states. Physical parameters of discrete states are\nconverted into formal R-matrix parameters, taking into account the potential\nbackground. The nuclear part of this potential is constructed by a new variant\nof an inversion method based on supersymmetric quantum mechanics. The method is\nillustrated on 12C + alpha S-wave elastic phase shifts.",
