研究了类钠Ａｒ７＋离子内壳层双电子的复合激发截面，此结果对研制Ｘ射线激光有一定的参考价值，并给出了２ｐ５３ｐ２和２ｐ５３ｄ２组态的双电子复合截面 The double-electron double-electron excitation cross-section of the inner-shell sodium-like Ar7 + ion shell has been studied. The results have certain reference value for the development of X-ray laser and the double electron recombination cross section of 2p53p2 and 2p53d2
