Abstract

We have performed the tunnel spectroscopy of the energy distribution function of quasiparticles in 5- μm-long silver wires connected to superconducting reservoirs biased at different potentials. The distribution function f(E) presents several steps, which are manifestations of multiple Andreev reflections at the NS interfaces. The rounding of the steps is well explained by electron-electron interactions.
