Phase slip in a narrow durty superconducting strip is studied theoretically using the Usadel formalism. Coordinate-dependent Green’s functions corresponding to the saddle point of the trajectory in the configuration space have been calculated, and the dependence of the free energy barrier on the transport current, magnetic field, and temperature has been obtained.
