Abstract
Assuming a ''two-peak'' characteristic phonon density of states for su perconductors it is shown that the deviation of the electron system fr om its equilibrium state may become substantially stronger compared wi th a well-studied ideal model for metals. If the charge carriers inter act with the transverse phonon modes, then the nonequilibrium deviatio n grows additionally and the creation of inversely populated states be comes possible.
