Interatomic or intermolecular Coulombic decay (ICD) is a nonlocal electronic decay
mechanism occurring in weakly bound matter. In an ICD process, energy released by …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

In pioneering work by Cederbaum et al an excitation mechanism was proposed that occurs
only in loosely bound matter (Cederbaum et al 1997 Phys. Rev. Lett. 79 4778): it turned out …

This review provides a comprehensive overview of the applications of helium nanodroplets
in the study of ensembles of atoms and molecules, ie clusters and complexes. These …

Nitrogen-bearing polycyclic aromatic hydrocarbons (PANHs) are ubiquitous in space. They
are considered precursors to advanced biomolecules identified in meteorites. However, their …

Autoionization is an important pathway for the relaxation of electronically excited states. In
weakly bonded matter, efficient autoionization channels have been found, in which not only …

Helium nanodroplets, commonly regarded as the 'nearly ideal spectroscopic matrix', are
being actively studied for more than two decades now. While they mostly serve as cold …

Abstract Short wavelength Free-Electron Lasers (FELs) are among the newest light sources
available to scientists to probe a wide range of phenomena, with chemical, physical and …

Photoionization spectroscopy and mass spectrometry of doped helium (He) nanodroplets
rely on the ability to efficiently detect ions and/or electrons. Using a commercial quadrupole …

The ionization dynamics of He nanodroplets irradiated with intense femtosecond extreme
ultraviolet pulses of up to 10 13 W/cm 2 power density have been investigated by …
