Total ionization cross-sections of atmospheric molecules due to electron impact

The total ionization cross-sections of atmospheric molecule due to electron impact for threshold ionization energy to 10 MeV have been studied. Many researchers like Khare and Wadhera [Phys Lett A, 198 (1995) 212] have successfully employed the Plane Wave Born Approximation (PWBA), corrected for the exchange, the Coulomb and the relativistic effects to calculate the outer shell ionization of molecules including transverse interaction for the inner shell ionization of atoms and molecules The present results have been compared with experimental data and other theoretical data wherever available.
