Cooper Instability

The possibility of the Cooper instability in transition metal compounds has been established on the bases of an idea about a strong interaction in a unit cell. The phase diagram of the superconducting ordering depending on a number of holes (hd) of the 3d-shells has been obtained. The non-phonon BCS constant has been calculated.
