摘要：

Anisotropies in the frustrated translational mode of CO chemisorbed on Cu(110) have been measured for the first time, with energies of 4.9 meV in the [1 (1) over bar 0] directions and 3.1 meV in the [001] directions. The measurements are made using a new time-of-flight ESDIAD (electron stimulated desorption ion angular distribution) method, permitting the resolution of bond directional effects and initial. state lateral momentum effects in ESDIAD patterns. These measurements provide a more detailed understanding of the librational potential energy well shape than has been possible previously.
