Inelastic-Electron-Scattering Cross-Section Measurements at 0.2-, 1.0-, and 2.0-MeV Incident Electron Energies

Spectra of inelastically scattered electrons from Al and Au targets are shown for scattering angles of 45 and 135 deg at incident electron energies of 0.2, 1.0, and 2.0 MeV, and for an angle of 60 deg at an energy of 1.0 MeV. Theoretical values from the Bethe-Heitler theory, calculated from the formulas of McCormick, Keiffer, and Parzen, are compared to the measured values.
