Abstract

The interaction of hydrogen and deuterium with the (OOO1) surface of beryllium has been investigated using resolution electron energy loss spectroscopy, thermal desorption spectroscopy, and work function measurements. Dissociative adsorption of molecular hydrogen is an activated process, and recombinative desorption occurs with an activation energy of ≈ 1 eV. No evidence for molecular adsorption is observed at substrate temperatures investigated ( 90 K). The binding site of atomic hydrogen and deuterium changes from bridge to tilted-bridge as the adsorbate coverage is increased above ≈ 0.4 monolayers.
