The emission of an Auger electron is the predominant relaxation mechanism of core-vacant
states in molecules composed of light nuclei. In this non-radiative decay process, one …

Energies and Auger widths of the LL resonances in He-like ions from boron to argon are
evaluated by means of a complex-scaled configuration-interaction approach within the …

The quantum chemical calculation of autoionisation resonances in many-electron systems is
a highly challenging task due to the ionisation continuum involved. Recently, advances were …

This work describes the implementation and applications of non-Hermitian self-consistent
field (NH-SCF) theory with complex basis functions for the ab initio computation of positions …

Absolute cross-sections for the K-shell photoionization of Be-like (O4+) and Li-like (O5+)
atomic oxygen ions were measured for the first time (in their respective K-shell regions) by …

Fano-ADC is a family of ab initio methods for the prediction of electronic decay widths in
excited, singly and doubly ionized systems. It has been particularly successful in elucidating …

We explore the merits of linear-response range-separated time-dependent density-
functional theory (TDDFT) for the calculation of photoionization spectra. We consider two …

Absolute cross sections for the K-shell photoionization of Be-like and Li-like atomic nitrogen
ions were measured by employing the ion–photon merged-beam technique at the SOLEIL …

Absolute cross sections for the K-shell photoionization of Be-like boron ions were measured
with the ion–photon merged-beams technique at the Advanced Light Source synchrotron …

We propose and develop the complex-scaled multiconfigurational spin-tensor electron
propagator (CMCSTEP) technique for theoretical determination of resonance parameters …
