Abstract
We study the density of states of the normal layer in the S-N-S proxim ity-contact systems in the clean limit, taking account of the finite r eflection at the interface as well as a possible pairing interaction i n the normal layer. The self-consistent pair potential and the density of states are calculated. It is found that when the normal layer has a repulsive pairing interaction, there occur additional states in the low energy range.
