Energy spectrum of superconductors with defects having spherical and cylindrical symmetry of their interaction potential with conduction electrons

Spatial behaviour of the ordering parameter in superconductors with defects is considered. Two cases are investigated: a) the point defect, for which the potential of interaction with conductivity electrons is rotationally invariant; b) the linear defect, for which the potential of interaction with conductivity electrons is invariant under the rotations with respect to the defect axis.
