摘要：

When the superconducting half of a superconductor-normal-metal film sandwich is a strong-coupling superconductor, phonon structure due to the superconductor (Pb)-but observed by tunneling into the normal metal (Ag)-provides a direct probe of the effective renormalization interaction in the normal metal. Unexpectedly, even fairly thick Ag films ( 350 ) backed by Pb exhibit effective renormalizations approaching that of Pb, both in overall strength and energy dependence. © 1979 The American Physical Society.
