Material ejected during (or immediately following) the merger of two neutron stars may
assemble into heavy elements through the r-process. The subsequent radioactive decay of …

Photoionization and its inverse, electron–ion recombination, are key processes that
influence many astrophysical plasmas (and gasses), and the diagnostics that we use to …

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 …

We present experimentally measured and theoretically calculated rate coefficients for the
electron-ion recombination of W 18+([Kr] 4 d 10 4 f 10) forming W 17+. At low electron-ion …

We review experimental and theoretical efforts aimed at a detailed understanding of the
recombination of electrons with highly charged tungsten ions characterised by an open 4f …

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 …

A brief review about topical developments in the exploitation of the resonant electron–ion
collision process of dielectronic recombination (DR) as a sensitive spectroscopic tool is …

Dielectronic recombination (DR) is a key atomic process that affects the spectroscopic
diagnostic modeling of tungsten, most of whose ionization stages will be found somewhere …

Highly excited eigenstates of atoms and ions with open f shell are chaotic superpositions of
thousands, or even millions, of Hartree-Fock determinant states. The interaction between …
