摘要
我们利用同步辐射设施 PETRA III 的单色软 X 射线光束线 P04 共振激发了氖型镍离子中最强的 2p-3d 转变：[2p6]J=0→[(2p5)1/23d3/2]J=1 和 [2p6]J=0→[(2p5)3/23d5/2]J=1 （分别称为 3C 和 3D ），分辨力达到 15 000，信噪比为 30。通过分析共振荧光光谱，我们得到了它们的自然线宽（精确度优于 10%）以及振荡器强度比 f(3C)/f(3D)=2.51(11)。这些结果与之前的实验、早期预测以及我们自己的高级计算结果一致。 美国物理学会出版 2024
Natural-linewidth measurements of the
3C
and
3D
soft-x-ray transitions in Ni xix
We used the monochromatic soft-x-ray beamline P04 at the synchrotron-radiation facility PETRA III to resonantly excite the strongest 2p−3d transitions in neonlike Ni ions, [2p6]J=0→[(2p5)1/23d3/2]J=1 and [2p6]J=0→[(2p5)3/23d5/2]J=1, respectively dubbed 3C and 3D, achieving a resolving power of 15 000 and signal-to-background ratio of 30. We obtain their natural linewidths, with an accuracy of better than 10%, as well as the oscillator-strength ratio f(3C)/f(3D)=2.51(11) from analysis of the resonant fluorescence spectra. These results agree with those of previous experiments, earlier predictions, and our own advanced calculations.Published by the American Physical Society2024
