It is shown experimentally that the nonequilibrium increment to the quasiparticle distribution function, due to the action of laser radiation on the superconductor, is located in an energy interval on the order of kT above the gap. The effect of ''blocking'' the states above the gap by the nonequilibrium quasiparticles leads to a decrease of the tunnel current in a narrow voltage interval at eVapproximately-greater-than2..delta...
