论文摘要
我们共同激发了$ k $系列的o $^{5+} $和o $^{6+} $，直达主量子数$ n = 11 $，带有单色X射线，产生$ k $ - 壳孔，并通过软X射线排放观察他们的放松。 o $^{5+} $的一些光吸附共振揭示了强的两电子 - 一photon（teop）过渡。我们发现，对于$ [（1S \，2s）_1 \，5p_ {3/2}] _ {3/2; 1/2; 1/2} $状态，Teop放松远比辐射衰减强，并且与通常更快的促进量衰减路径竞争。这种增强的teop衰变是由与近定位上层状态的密切相关性$ [（1S \，2p_ {3/2}）_ 1 \，4S] _ {3/2; 1/2; 1/2; 1/2; 1/2; 1/2} $ he-like he-like satellite Blend of He-like $kα$ kin $ triverition。即使在三电子系统中，TEOP转变也可以起到主导作用，目前的结果也应指导对无处不在和丰富的多电子离子的进一步研究，在该研究中，这些电子脱位更为普遍，并且构型混合更加强。
We resonantly excite the $K$ series of O$^{5+}$ and O$^{6+}$ up to principal quantum number $n=11$ with monochromatic x rays, producing $K$-shell holes, and observe their relaxation by soft-x-ray emission. Some photoabsorption resonances of O$^{5+}$ reveal strong two-electron--one-photon (TEOP) transitions. We find that for the $[(1s\,2s)_1\,5p_{3/2}]_{3/2;1/2}$ states, TEOP relaxation is by far stronger than the radiative decay and competes with the usually much faster Auger decay path. This enhanced TEOP decay arises from a strong correlation with the near-degenerate upper states $[(1s\,2p_{3/2})_1\,4s]_{3/2;1/2}$ of a Li-like satellite blend of the He-like $Kα$ transition. Even in three-electron systems, TEOP transitions can play a dominant role, and the present results should guide further research on the ubiquitous and abundant many-electron ions where electronic energy degeneracies are far more common and configuration mixing is stronger.
