A theory of the nonstationary Josephson effect in SNS junctions with low impurity density is constructed on the basis of the microscopic equations of superconductivity theory. The general expressions obtained for the current are used to determine the linear response of the system to a small alternating voltage, the stimulation of the critical contact by microwave irradiation is investigated, and the nonstationary Josephson effect is analyzed at low and high voltages. The decisive role in the nonstationary behavior of SNS junctions is played by the disequilibrium of the quasiparticle distribution in the system; this disequilibrium leads, in particular, to an essentially nonsinusoidal I(phi) dependence at all T and d.
