报道了高电荷态Ar、Fe和Kr离子的壳层间高阶电子复合,其中一个自由电子的共振俘获同时激发一个K壳层电子和一个或两个额外的L壳层电子。对于中Z区,Ho共振强度随着原子序数Z(∝Z(-4))的减小而出人意料地增强,因此,对于Ar离子,二阶共振强度大大超过了一阶共振复合。多组态Dirac-Fock计算证实了实验结果,其中包括迄今被忽略的激发路径。
Intershell higher-order (HO) electronic recombination is reported for highly charged Ar, Fe, and Kr ions, where simultaneous excitation of one K-shell electron and one or two additional L-shell electrons occurs upon resonant capture of a free electron. For the mid-Z region, HO resonance strengths grow unexpectedly strong with decreasing atomic number Z (∝Z(-4)), such that, for Ar ions the 2nd-order overwhelms the 1st-order resonant recombination considerably. The experimental findings are confirmed by multiconfiguration Dirac-Fock calculations including hitherto neglected excitation pathways.
