X-ray and ultraviolet (UV) observations of the outer solar atmosphere have been used for
many decades to measure the fundamental parameters of the solar plasma. This review …

Electron–ion collisions are among the most important atomic processes in ionized gases.
They comprise elastic scattering, excitation, ionization, and recombination. Theoretical …

Aims. The goal of the CHIANTI atomic database is to provide a set of atomic data for the
interpretation of astrophysical spectra emitted by collisionally dominated, high temperature …

A programme is outlined for the assembly of a comprehensive dielectronic recombination
database within the generalized collisional–radiative (GCR) framework. It is valid for …

We have calculated partial final-state resolved radiative recombination (RR) rate coefficients
from the initial ground and metastable levels of all elements up to and including Zn, plus Kr …

Reliably interpreting spectra from electron-ionized cosmic plasmas requires accurate
ionization balance calculations for the plasma in question. However, much of the atomic …

A review of the current status of the theoretical study of spectral line profile for systems with
few electrons is given in this paper. The hydrogen atom and highly charged ions are …

A unified treatment for electron-ion recombination has been developed and applied to
detailed calculations for cross sections and total recombination rate coefficients for a number …

The close-coupling approximation for electron-atom scattering is extended to include the
effect of one-photon radiation damping at a level nonperturbative in the wave function. The …

Electron-impact ionization cross sections for all atomic ions in the W isonuclear sequence
are calculated using a variety of theoretical methods. For the direct ionization process, a …
