Abstract The anisotropic order parameter case of the two‐band superconductivity model with driving pair scattering between overlapping bands is investigated. The s + d‐type interaction used can lead to mixed and also pure d‐ or s‐wave order parameters. The behaviour of T c and order parameter symmetry change with chemical potential are illustrated. Also the dependences of gap symmetry components on temperature and chemical potential have been obtained. The singularities in the electronic spectra are reflected in T c .
