Core excitations of uranyl in CsUOCl from relativistic embedded damped-response time-dependent density functional theory calculations

Wilken Aldair Misael, André Severo Pereira Gomes

X-ray spectroscopies, by their high selectivity and sensitivity to the chemical environment around the atoms probed, provide significant insight into the electronic structure of mo…

Relativistic Embedded Equation-of-Motion Coupled-Cluster Approach to the Core-Ionized States of Actinides: A Case Study of Uranyl(VI) in CsUOCl

Wilken Aldair Misael, Andre Severo Pereira Gomes

We investigate the core-level ionization energies of the bare uranyl ion (UO) and its interaction with X-rays when it is hosted in the CsUOCl crystalline envir…
