The electron loss spectra of the solid rare gases for low primary beam energies

The high resolution electron energy loss spectra of solid xenon, solid krypton and solid argon have been measured at 10K with primary beam energies in the range 100 to 1000 eV. The spectra are interpreted in terms of excitons, plasmons, interband transitions and ionizations of inner shells. The classifications of the lower resolution differential spectra of Farrell and Strongin (1972) have been clarified and extended.
