Abstract

We discuss first the preparation, handling and characterization of bulk and thin films of PdHx and PdDx. We show how information concerning the electron-phonon coupling can be extracted from the temperature dependant normal state resistivity. Particular emphasis will be drawn on the way of separating the acoustical and optical contribution to this coupling. Experimental resistivity data concerning PdHx and PdDx, supplemented by some supraconducting tunneling data will be presented. Finally we will discuss the possible origin of the positive isotope effect observed for the superconducting Tc and the influence of magnetic impurities on Tc.
