Abstract
The tunneling characteristics of an aluminum-aluminum
oxide-mercury junction have been measured at
temperatures down to Oo35°K. Additional structure over
that seen in an earlier, higher-temperature experiment is
reported. The data have been analyzed through the use of
a computer program based on the strong-coupling theory.
The effective phonon spectrum and the complex energy gap
function for mercury are thereby derived. Values for the
electron self energy function, the electron renormalization
function, Coulomb pseudopotentia1, and the electron-phonon
interaction constant are also determined.
