Electron-impact excitation and ionization of complex atoms
TL;DR: In this paper, the state-of-the-art in this field is illustrated by a few key examples of the current state of the art in the field of electron impact excitation and ionization processes.

The high partial wave phenomenon of spin changing atomic transitions
TL;DR: In this article, the collisional transition between two highly excited atomic states with different spin is investigated theoretically, and it is shown that the transition is driven in the highly ionized Fe ion purely by exchange, and the cross section becomes increasingly dominated by partial waves of high orbital angular momentum as the scattering energy increases.

Recombination Lines of CII in the Spectra of Planetary Nebulae
TL;DR: In this article, two CIII targets were prepared and used to generate theoretical data required in the investigation of recombination lines that arise from collisions between electrons and ions in thin plasma found in planetary nebulae and other astrophysical objects.

GRASP: A general-purpose relativistic atomic structure program
TL;DR: The Oxford MCP/MCDF and MCBP/BENA packages have been rewritten in FORTRAN 77 and combined in the new code, GRASP, which is more versatile than its predecessors, contains more stable and accurate numerical procedures and a simplified but more flexible interface.

Quantum defect theory
TL;DR: Quantum defect theory (QDT) as mentioned in this paper is a unified theory of bound states, including series perturbations, autoionisation and electron-ion scattering, both elastic and inelastic.
