类氖原子体系的高激发态（偶宇称）

Highly-excited States with Even Parity for Neon-like

在计及自旋－轨道相互作用和组态相互作用条件下，用本征通道量子亏损理论（ＥＱＤＴ）方法系统地计算了氖等电子序列（从ＮｅＩ到ＣａＸＩ）偶字称的高激发态结构。所得结果与已有的实验数据符合得很好。

The basic structure parameters of 2p￣5(￣2P)nl(l = p and f)Rydberg spectra of the neonlikeatomic systems from Ne I to Ca XI as function of the effective nuclear charge were calculated by usingthe eigenchannel quantum-defect theory(EQDT).As a numerical example,we gave the energy levelswith J=1 and Lu-Fano plots with J=O and 2 for Ne I using its structure parameters as input. Theresults indicated that the isoelectronic behaviour of the chnnel interaction can bge interpreted interms of the competition between electrostatic and spin-orbit interactions with the increasing value ofnuclear charge.
