Site and interaction dependence of nuclear stimulated desorption from structured surfaces

Molecular dynamics calculations of low energy Nuclear Stimulated Desorption (NSD) of Cd-107 from a palladium substrate are presented. The characterist ics of the desorption probability are shown to be related both to the site occupied by the Cd-107 and to the adsorbate-substrate interaction. The quan titative implications of the theoretical calculations to a specific experim ental scenario are discussed, based on preliminary measurements of Cd-107 d esorption from palladium.
