Abstract

The backscattering-channeling spectrum exhibits a surface peak corresponding to the interaction of the beam with the first monolayer(s) of the crystal. Using Monte Carlo techniques we have calculated the surface peak intensity for a wide range of experimental conditions. We show that the results can be expressed as a function of one parameter, thus permitting the generation of an almost universal curve for surface peak estimates. The results are in reasonable agreement with experiment. A method of background subtraction from the surface peak is also discussed.
