Abstract

The cross section of inner-shell excitation followed by auto-ionization and total ionization cross section of lithium-like ions by electron impact have been calculated by using a distorted wave Born exchange approximation. The comparison of present data with close-coupling calculation and experimental measurement is satisfactory.
