Abstract The COLTRIMS Reaction Microscope C‐REMI can image the momentum vectors of
all emitted charged fragments in an atomic or molecular reactions similar to the bubble …

The field of angle-resolved molecular photoelectron spectroscopy is reviewed, with
emphasis on foundations and most recent applications in different regimes of light–matter …

Ultrashort x-ray pulses from free-electron lasers can efficiently charge up and trigger the full
fragmentation of molecules. By coincident detection of up to five ions resulting from rapid …

We publish three Roadmaps on photonic, electronic and atomic collision physics in order to
celebrate the 60th anniversary of the ICPEAC conference. In Roadmap I, we focus on the …

Since spring 2019 an experimental setup consisting of an electron spectrometer and an ion
time-of-flight mass spectrometer for diluted samples has been available for users at the …

Auger electrons can be highly radiotoxic when they are used to irradiate specific molecular
sites. This has spurred basic science investigations of their radiobiological effects and …

In this combined theoretical and experimental study we report a full analysis of the resonant
inelastic X-ray scattering (RIXS) spectra of H2O, D2O and HDO. We demonstrate that …

Molecules can sequentially absorb multiple photons when irradiated by an intense X-ray
pulse from a free-electron laser. If the time delay between two photoabsorption events can …

We study vibrationally-resolved resonant Auger (RAS) spectra of ammonia recorded in
coincidence with the NH2+ fragment, which is produced in the course of dissociation either …

We present here a review of the most significant recent achievements in the field of HAXPES
(hard x-ray photoelectron spectroscopy) on isolated atoms and molecules, and related …
