中文摘要：
在相对论多组态Dirac-Fock理论方法基础上,通过系统考虑电子关联效应、弛豫效应以及相对论高阶修正,详细研究了CⅡ离子1s-2p光激发形成的内壳层电子激发态（1s2^s22p^2和1s2s2p^3）、辐射和Auger末态的能级结构以及各种可能的衰变过程.计算了CⅡ离子1s内壳层光激发能量、辐射和Auger衰变率及其线宽,进一步由不确定关系推出了这些激发态的能级寿命,并与最新的实验结果和已有的理论结果进行了比较.
英文摘要：
Based on the multi-configuration Dirac-Fock method,the level structures and decay processes of the inner-shell excited states（1s2s22p^2 and 1s2s2p^3）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.
