The exploration of the unique properties of stored and cooled beams of highly-charged ions
as provided by heavy-ion storage rings has opened novel and fascinating research …

The photon-ion merged-beams technique for the photoionisation of mass/charge selected
ionised atoms, molecules and clusters by x-rays from synchrotron radiation sources is …

New capabilities at X-ray free-electron laser facilities allow the generation of two-colour
femtosecond X-ray pulses, opening the possibility of performing ultrafast studies of X-ray …

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 …

Single, double, and triple photoionization of Ne+ ions by single photons have been
investigated at the synchrotron radiation source PETRA III in Hamburg, Germany. Absolute …

Single, double, and triple ionization of C 1+ ions by single photons is investigated in the
energy range of 286–326 eV, ie, in the range from the lowest-energy K-vacancy resonances …

Absolute cross-sections for m-fold photoionization (= ¼ m 1,, 6) of Fe+ by a single photon
were measured employing the photon–ion merged-beams setup PIPE at the PETRAIII …

Using the photon–ion merged-beams technique at a synchrotron light source, we have
measured relative cross sections for single and up to five-fold photoionization of Fe 2+ ions …

We report on new measurements of m-fold photodetachment (m= 2-5) of carbon anions via
K-shell excitation and ionization. The experiments were carried out employing the photon …

Carbon 1s core‐hole excitation of the molecular anion C2− has been experimentally studied
at high resolution by employing the photon‐ion merged‐beams technique at a synchrotron …
