Abstract

A detailed study, using molecular dynamics, of O₂ desorption from Ag(110) following a collision with "hot" oxygen atoms is presented. The interactions in the system are described by semiempirical model potentials. The variation of desorption yield and desorbate angular and energy distributions as a function of "hot" atom energy and surface coverage is examined. The computational results clearly show that the collision induced desorption, following photo-induced dissociation of O₂, is a plausible explanation of the experimental findings. The coverage dependence of collision induced desorption cross section and the angular distribution of desorbates agree well with the corresponding measured quantities.
