We have measured the tunneling characteristics of a series of Al-oxide-(Ag 1-xErx)Pb proximity effect sandwiches for normal metal thicknesses ranging from 500 A to 3 000 A and parallel magnetic fields of 0-1 000 gauss. Second derivative characteristics (d2V/dI2) reveal the Pb phonon structure through electron interference effects and also reveal structure at the Ag phonon frequencies. Application of a magnetic field less than the critical field of the sandwhich reduces the Ag phonon structure. Introduction of impurities reduces the interference effects with little effect on the Ag phonon structure. We are thus able to separate the two contributions to the tunnelling characteristics. Comparison with the theory of McMillan and Rowell then all...
