摘要

对原始钚 N4,5 和 O4,5 X 射线吸收光谱（XAS）进行了详细的光谱模拟。此外，还纠正了电子能量损失光谱（EELS）测量中的一个基本缺陷。因此，对元素钚中 5f 占位 (n) 的测定进行了重新评估，结果是 αPu 的 n = 5.0 ± 0.1，δPu 的 n = 4.9 ± 0.2。这些数值明显低于先前传播的 ∼5½ 值。

A reassessment of 5f occupation in plutonium

A detailed spectroscopic simulation of the original Pu N_4,5 and O_4,5 X-Ray Absorption Spectroscopy (XAS) has been performed. Additionally, a fundamental flaw in the Electron Energy Loss Spectroscopy (EELS) measurement has been corrected. Thus, the determination of the 5f occupation (n) in elemental Pu has been re-evaluated with the result that n = 5.0 ± 0.1 for αPu and n = 4.9 ± 0.2 for δPu. These values are significantly lower than the value of ∼5½ that was propagated earlier.
