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
期刊介绍：
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
