Distortion due to static interactions, target polarization and exchange effects has been incorporated in the initial channel. The present calculations have been compared with other theoretical and experimental results. the Indian Academy of Sciences, 1992 Coulomb-projected Born method nationallicence distorted wave nationallicence electron impact excitation nationallicence exchange potential nationallicence target polarization nationallicence 34·80 nationallicence Kumar V.
