The electronic structure of CeNiSb3 probed with XAS and XES

Rare earth antimonides have drawn interest because of their important physical properties and bonding. A relatively new member of this family of materials is CeNiSb$_{3}$. Previous dependent resistivity measurements exhibit a behavior typical for magnetically Kondo lattices with a localized $f$ moment weakly coupled with the conduction band. X-ray absorption (XAS) and emission spectroscopy (XES) measurements of the Ce 3$d$ and Ce 4$d$ have been performed. These measurements probe the $p$ to $d$ and $f$ to $d$ transitions and the density of states from these measurements will be presented.
