Accurate He-Ag(110) interaction potential determination by selective adsorption
Abstract
The first accurate energy level measurements of a He-metal interaction potential are reported for the Ag(110) surface as obtained from selective adsorption data. The fitting of the experimental data with a suitable phenomenological potential leads to a well depth of 6.0 ± 0.1 meV. The potential curve is considerably softer than those obtained for He interaction with either insulators or semiconductors and is in good agreement with theoretical predictions.
