Electron impact single and double ionization cross-sections for
magnesium have been calculated in the binary encounter model using
accurate expression for (cross-section for energy transfer
) as given by
Vriens. Hartree-Fock velocity distributions for the target electrons have been
used throughout the calculations. In case of double ionization contributions
of inner shell ionization and Auger emission have been included in the
present work. The results obtained in case of single ionization are excellent
and at the same time the double ionization cross-sections show reasonably
good agreement with the recent experimental observations. Substantiation of
the viewpoint of Peach, and Boivin and Srivastava that a vacancy in the 2p
shell of magnesium leads to double ionization is a remarkable feature of the
present investigation.
