Resonant inelastic x-ray scattering (RIXS) is a major method for investigation of electronic
structure and dynamics, with applications ranging from basic atomic physics to materials …

We have performed x-ray two-photon photoelectron spectroscopy using the Linac Coherent
Light Source x-ray free-electron laser in order to study double core-hole (DCH) states of CO …

The x-ray absorption spectrum of N 2+ in the K-edge region has been measured by
irradiation of ions stored in a cryogenic radio frequency ion trap with synchrotron radiation …

We present the implementation of an electronic-structure approach dedicated to ionization
dynamics of molecules interacting with x-ray free-electron laser (XFEL) pulses. In our …

Lithium–sulfur (Li–S) batteries are considered candidates for next-generation energy
storage systems due to their high theoretical specific energy. There exist, however, some …

We have measured the vibrational structures of the N 1 s photoelectron mainline and
satellites of the gaseous N 2 molecule with the resolution better than 75 meV⁠. The gerade …

State-of-the-art argon KLL Auger spectra measured using photon energies of h ν= 3216 and
3400 eV are presented along with an Ar [1 s] photoelectron spectrum (square brackets …

Theoretical description of potential energy curves (PECs) of molecular ions is essential for
interpretation and prediction of coupled electron-nuclear dynamics following ionization of …

Experimental near-edge x-ray-absorption fine-structure (NEXAFS) spectra of the nitrosonium
NO+ ion are presented and theoretically analyzed. While neutral NO has an open shell, the …

The theoretical description of core-hole and core-hole excited (shake-up) states resulting
from the interaction of a molecule with X-ray free-electron lasers, attosecond pulses, and …
