Palladium alloy hydrides and deuterides have been fabricated using the low temperature ion implantation method. The superconducting transition temperatures (T/sub c/) have been found to increase in a systematic way when small amounts of post-transition metals are added to the palladium hydride system. By assuming that the optical phonon contribution of hydrogen (deuterium) is chiefly responsible for the changes in T/sub c/ in these materials, it is shown that the observed superconducting properties, including an inverse isotope effect, may be correlated with normal state resistivity measurements. A limited set of experiments has also been made on ion-implanted molybdenum-based and aluminum-based materials.
