Compton Scattering of High-Energy Electrons from Helium

The electron-impact energy-loss spectrum of He at a scattering angle of 7\ifmmode^\circ\else\textdegree\fi{} has been measured with an energy resolution of 2.7 eV full width at half-maximum using 25-keV incident electrons. A binary-encounter approximation was used to obtain the electron Compton profile from the cross-section differential with respect to both the energy loss of the incident electron and solid angle of the scattered electron...
