The ejected-electron spectrum of sodium vapour autoionizing levels excited by 35 to 400 eV electrons

Abstract
The ejected-electron spectrum of sodium vapour has been observed at angles up to 120 degrees C with respect to an incident electron beam of kinetic energy 35 to 400 eV. Comparisons are made with ultraviolet absorption data and ejected-electron spectra obtained by electron and proton impact excitation.
