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 …

Sources of uncertainty are reviewed for calculated atomic and molecular data that are
important for plasma modeling: atomic and molecular structures and cross sections for …

The nebular phase of lanthanide-rich ejecta of a neutron star merger (NSM) is studied by
using a one-zone model, in which the atomic properties a represented by a single species …

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 …

Electron-impact single-ionization cross sections for the W 5+ ion have been studied
experimentally and theoretically. Measurements of a detailed ionization spectrum and of …

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

In the past two decades, the electron–ion merged-beams technique has extensively been
exploited at heavy-ion storage rings equipped with electron coolers for spectroscopic …

Collisional processes and details of atomic structure of heavy many-electron atoms and ions
are not yet understood in a fully satisfying manner. Experimental studies are required for …

Experimental and theoretical results are reported for photoionization of Ta-like (W+)
tungsten ions. Absolute cross sections were measured in the energy range 16–245 eV …

Experimentally measured and theoretically calculated rate coefficients for the recombination
of W 19+([Kr] 4 d 10 4 f 9) ions with free electrons (forming W 18+) are presented. At low …
