I have calculated double ionization cross sections of silicon and phosphorus by electron impact using double binary encounter model. Hartree-Fock momentum distribution has been used for both the ejected electrons during collision process. Contributions from inner shell in the double ionization have been included in the calculations. The results obtained have been found in reasonably good agreement with the experimental observations.
