摘要
In this short article, the accurate labeling of the O-4,O-5 edges of the light actinides is addressed. The O-4 and O-5 edges are both contained in what is termed the 'giant resonance' and the smaller 'pre-peak' that is observed is a consequence of first-order perturbation by the 5d spin-orbit interaction on the 5d,5f exchange splitting. Thus, the small pre-peak in the actinide 5d --> 5f transition should not be labeled the OS peak, but rather the Delta S = 1 peak. (c) 2007 Elsevier B.V. All rights reserved.
