Abstract

Using Pb on Nb3Sn tunnel junctions we measure the phonon-induced deviations from the BCS density of states. The overall strength of the deviations decreases but the shape does not change appreciably over the composition range from 25 at.% Sn (high Tc, strong-coupling) to 20 at.% Sn (low Tc, weak-coupling)
