    • Abstract

       

      The Coulomb-Glauber approximation is applied to evaluate the electron-impact excitation integrated cross sections for 11S —n1P (n=2, 3) transitions in helium-like ions, C4+, N5+, O6+ and Ne8+. The results are presented in terms of scaled collision strengthn3Z2ki2σ and scaled integrated cross-sectionZ4σ. Our values when compared with other available theoretical results are found to be larger than the Coulomb-Born and distorted wave polarised orbital (DWPO) values.
