Based on the multi-configuration Dirac-Fock method, the level structures and decay processes of the inner-shell excited states 1s2s22p2 and 1s2s2p3 created by 1s-2p photoexcitation of C Ⅱ ion have been studied systematically, which the correlation and relaxation effects, relativistic radiative corrections have been considered in the calculations. Auger and radiative transition energy, decay rate and linewidth for each inner-shell excited states of C Ⅱ ion has been calculated. Correspondingly, lifetimes of those autoionization states can be obtained via the Heisenberg uncertainty principle. A comparison of the present calculations with the latest experimental and available theoretical results is also presented.
