摘要
The K-shell cross-section sigma k( alpha ) for 80 kV electrons traversing thin single crystals of graphite and aluminium nitride is measured from electron energy-loss spectra generated within an energy-selecting electron microscope. These values, and the variation with collection semi-angle alpha , are compared with values derived from Bethe theory for an isolated atom.
