1s22pns(P01) autoionizing levels in Be-like Al and C ions
TL;DR: In this article, the authors used the R-matrix Floquet theory and codes and its extension to laser induced degenerate state to describe dielectronic recombination of Li-like into Be-like ions.

Atomic data from the IRON Project - XLIX. Electron impact excitation of Fexx
K. Butler,C. J. Zeippen +1 more
TL;DR: In this article, collisional data between 86 levels of the N-like iron complexes were obtained in a Breit-Pauli relativistic approximation and include resonance contributions by the use of close-coupling wavefunctions.

Photoionization of O III low-lying states: autoionization resonance energies and widths of some 1s-2p excited states
TL;DR: In this paper, the inner-shell photoionization of the terms belonging to the configurations 2s22p2 and 2s2p3 of the O III ion was analyzed and the resonance energies and widths of the transitions of a 1s electron excited into the 2p orbital were determined by analysing the resonance structures of the photoionisation cross sections.

Total cross sections for the double photoionization of Li from the ground and excited states
TL;DR: In this article, two nonperturbative approaches are used to calculate the total cross sections for the double photoionization of Li from its ground and first excited states, and both the time-dependent close coupling and matrix with pseudostate approaches find reasonable agreement with experimental data.

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.
