S+D SYMMETRY ORDER PARAMETERS IN INTERBAND SUPERCONDUCTIVITY

The anisotropic order parameter case of the two-band superconductivity model with driving pair scattering between overlapping bands is inves tigated. The sf d-type interaction used can lead to mixed and also pur e d- or s-wave order parameters. The behaviour of T-c and order parame ter symmetry change with chemical potential are illustrated. Also the dependences of gap symmetry components on temperature and chemical pot ential have been obtained. The singularities in the electronic spectra are reflected in T-c.
