Abstract
Superconducting tunneling experiments on niobium single crystals with indium and lead‐bismuth counterelectrodes show an isotropic energy‐gap value of 3.12±0.05 meV, or 3.93kTc, for 26 junction orientations. Self‐consistent analysis criteria have been developed for the determination of gap values. These criteria are not met in the existing literature on transition‐metal tunneling.This publication has 2 references indexed in Scilit:
