Abstract
The tunneling probability for a positive muon in high-purity tantalum is significantly enhanced by the onset of superconductivity. This esta blishes the predominant influence of low energy infrared couplings to the conduction electrons in the quantum tunneling motion of a charged interstitial atom in metals.
