Abstract

We report first differential cross-section measurements for inner-shell ionization of surface atoms by electron impact. Comparison is made with calculations derived from a simple extension of the Burhop theory for ionization of isolated atoms. The trends of the predicted values are in qualitative agreement with experiment.
