Abstract
A LEED study of the (110) surface of palladium using a Data-Quire video-LEED system has determined that the laterally unreconstructed layers of Pd(110) have an oscillatory relaxation with respect to the bulk interlayer spacing. The first and second interlayer spacings were found to be -5.7+or-2% and +0.5+or-2%, respectively, with respect to the bulk spacing. These results agree reasonably well with recent embedded-atom theory results which predict a first-layer contraction of about 11%. The possible role of surface disorder in surface relaxation is discussed.Keywords
