By using M4, 5 X-ray Emission Spectroscopy (XES) in the tender X-ray regime, it is possible
to quantify 5f delocalization in the actinides. Previous analyses, utilizing the Branching Ratio …

Recently, X-ray absorption spectroscopy (XAS) and related derivative measurements have
been used to demonstrate that the Pu 5f states are strongly relativistic and have a 5f …

Delocalization in the 5f states of the actinides is an important phenomenon, but poorly
quantified. Here, the fundamental limitations of 5f dispersion measurements using angle and …

Based solely upon the previously reported (1) Bremsstrahlung Isochromat Spectroscopy
(BIS) data for αU and (2) the known values for the 5f5/2 and 5f7/2 populations of αU, it is …

Perhaps the most demanding and powerful actinide spectroscopy is that using soft X-ray
and VUV photons. Because of the relatively low energy and fairly small sampling depths of …

Uranium and Plutonium are highly reactive elements that undergo not only chemical
reactions but also nuclear reactions. This can lead to possibly significant materials …

We investigate the effect of many-body interactions on the spin–orbit coupling of anisotropic
metals. We use the underscreened Anderson lattice model that was proposed to describe …

Abstract Bremstrahlung Isochromat Spectroscopy (BIS) has a proven record for the probing
of unoccupied electronic structure, including feasibility studies of actinides such as U and …

The nature and limitations of the photoelectron spectroscopy (PES) of Pu is discussed,
particularly the absence of detailed fine structure. A novel experiment, Fano Spectroscopy, is …

We investigate the effect of many-body interactions on the spin-orbit coupling of anisotropic
