Abstract
It is sporadically documented in the literature that the electron-phonon in- teraction is much weaker than expected in the superconducting state in metals. Owing to a tendency to explain it away this observation has so far gone under-recognized. By applying a straightforward numerical procedure to normal state resistivity and superconducting tunneling conductance experimental data the atomic potentials in tantalum, niobium, lead and aluminum are revealed to be consistently weaker in the superconducting state than in the normal state.
