Title: Electronic and cluster effects in films of gadolinium-copper alloys in the low-temperature homomolecular exchange of hydrogen

Abstract

In the authors previous work, they discovered a sharp increase in the specific catalytic activity (K/sub sp/) relative to the low-temperature homomolecular isotropic exchange of hydrogen upon copper. In this work, this study was continued for the Gd-Cu system. They investigated the specific catalytic activity of the films obtained by the complete atomization of a sample of the intermetallide GdCu/sub 6/ and the change in the K/sub sp/ upon gradual atomization. A study was also carried out on the change in the composition of the film over its depth by x-ray photoelectron spectroscopy in conjunction with ionic etching. The area of the surface obtained was measured relative to hydrogen adsorption at -196/sup 0/C and then the rate of the ortho-para conversion of hydrogen was measured at this temperature. Subsequently, the rate of the H/sub 2/-D/sub 2/ isotope exchange was studied at from -196 to -30/sup 0/C.
