NONEQUILIBRIUM PHENOMENA IN Sn-Sn-PbBi SYSTEM PLACED IN VARIOUS SAMPLE SURROUNDINGS

Nonequilibrium superconductivity and intermediate states in Sn-Sn-PbBi system have been studied in different sample surroundings of vacuum, gas helium, and liquid helium. General behaviors under quasiparticle injection are presented. Nonequilibrium quasiparticle distribution function is modeled by the μ* - T* scheme, and the phonon trapping factor τ_es/τ_B is calculated through R-T equations.
