摘要

在利弗莫尔的EBIT-I电子束离子阱上,在受控的实验室条件下,使用x射线量热计测量了类氟铕离子(Eu54+)的l壳层x射线发射,将这种测量扩展到稀土元素的中间。将量热计光谱与柔性原子代码中的原子数据进行比较,我们发现并分析了几个突出的n = 3→n = 2跃迁,包括一个双电子、单光子核心变化跃迁和一个电四极跃迁。我们发现测量的能量始终比预测的高几个eV。

Measurements of the L-shell x-ray emission of fluorinelike europium
Measurements of the L-shell x-ray emission of fluorinelike europium ions (Eu54+) were made under controlled laboratory conditions on the EBIT-I electron beam ion trap at Livermore using an x-ray calorimeter, extending such measurements to the middle of the rare earth elements. Comparing the calorimeter spectra with atomic data from the Flexible Atomic Code, we have identified and analyzed several prominent n = 3 → n = 2 transitions, including one two-electron, one-photon core changing transition and one electric quadrupole transition. We find that the measured energies are consistently up to several eV higher than predicted.
