摘　　要：利用多组态Dirac_Fock(MCDF)理论方法,通过对Ar原子在基组态3p6和激发组态1s^(-1)4s,2s^(-1)4s,2p^(-1)4s,3s^(-1)4s,3p^(-1)4s情况下电子波函数的计算,系统地研究了不同内壳层电子激发(或电离)引起的电子波函数的弛豫现象以及由此导致的kα和kβ线的跃迁波长和概率的变化情况,并与以往的理论结果进行了比较.The relaxation effects induced by excitation （or ionization） of inner subshell electrons and their influences on the electronic wave functions of the ground configuration 3p6 and five excited configurations 1 s^- 1 4s, 2s^ -14 s, 2p^-1 4s, 3s^-1 4s, and 3p^- 1 4s in Argon have been systematically studied by using the Multi-configuration Dirac-Fock method （MCDF）. Furthermore, the transition energies and probabilities of argon from kα and kβ lines have been presented and discussed in cases with and without relaxation, and also a comparison has been made with some existing theoretical calculations.
