Ejected-electron spectrum of Mg I and Mg II autoionising levels between 20 and 53 eV excited by low-energy electron impact on magnesium vapour

The ejected-electron spectrum of magnesium vapour has been observed at 75 degrees with respect to an incident electron beam of 62 to 400 eV incident energy. Ejected electrons corresponding to both Mg I autoionising levels and Auger transitions are reported. Comparison is made with photoabsorption data, ejected-electron spectra from ion impact and high-energy electron impact experiments and available theoretical calculations.
