Abstract

It is clear from the scope of this symposium that major advances have been achieved in our ability to detect and characterize the uncharged species that desorb from ion bombarded surfaces. The use of plasma sources and lasers have been particularly useful in enhancing the sensitivity of detection over the traditional weight-loss methods. In this paper, we describe the use of multi-photon resonance excitation as a post-ionization technique for detecting desorbed neutrals with high sensitivity and selectivity. The discussion will focus on where this approach is most likely to be successful and where it should probably not be utilized. Examples of present applications will be cited,with a special emphasis on the use of laser techniques to determine the energy and angle distributions of particles emitted from single crystals.
