Popis:	The proximity effect in Pb/Sn sandwich under the impact of quasiparticle tunnel injection has been studied. The estimation of the γ and γBN proximity effect parameters has been made; the dependence of the γ and γBN parameters on the Sn thickness has been built. It has been shown by studying the current-voltage characteristics of the double-barrier tunnel junction with a Pb/Sn intermediate proximity electrode that an increase of the γm parameter of the strength of the proximity effect occurs as a result of quasiparticle tunnel injection into the Pb/Sn proximity electrode.
