Improved collision strengths and line ratios for forbidden [O III] far-infrared and optical lines
TL;DR: In this article, Breit-Pauli R-matrix calculations for the collision strengths with highly resolved resonance structures are presented. But despite their importance in nebular diagnostics collision strengths for the associated fine structure transitions have not been computed taking full account of relativistic effects.

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.
