The inner-shell excitation ls22s2se--~ls2822S e, which leads to autoionization (Auger transition), as well as the outer-shell excitation ls22s 2Se--* 1 s22p 2po transitions have been investigated in Li, Be +, B ~ + and C 3 + ions of the lithium isoelectronic sequence employing the configuration interaction wave functions for both the initial and final states involved in the transition matrix element. Results are compared with other available theoretical predictions and experimental observations. Comparison shows that our present theoretical results are encouraging.PACS 31.10 -General theory of electronic structure, electronic transitions, and chemical binding.
