Abstract
We report measurements on superconducting tunnel junctions illuminated with optical radiation, which confirm the model of nonequilibrium superconductors proposed by Owen and Scalapino. Measurements of the chemical potential ${\ensuremath{\mu}}^{*}$ for quasiparticle excitations and of the temperature dependence of the quasiparticle recombination time are presented.
