Electron-impact excitation of Ar+: an improved determination of Ar impurity influx in tokamaks
TL;DR: In this article, a 452-term R-matrix with pseudo-state (RMPS) calculation of electron-impact excitation for Ar+ was performed to provide more accurate excitation data.
Journal ArticleDOI
Energy levels, radiative rates and electron impact excitation rates for transitions in C iii
TL;DR: In this paper, the authors report energy levels, radiative rates (A-values) and lifetimes for the astrophysically important Be-like ion C III, for all E1, E2, M1 and M2 transitions.

Transition Probabilities and Electron Excitation Rates for Fe XIV
TL;DR: In this article, the Breit-Pauli R-matrix approach was used to calculate the impact rate and oscillator strength for the transition from Fe XIV lines to the 3s23p, 3s3p2 and 3s 3p3d configurations.

Importance of the completeness of the configuration interaction and close coupling expansions in R-matrix calculations for highly-charged ions: electron-impact excitation of Fe $^{20+}$
TL;DR: In this article, the same authors carried out two intermediate coupling frame transformation (ICFT) R-matrix calculations for the electron-impact excitation of C-like Fe, both of which use the same expansions for their configuration interaction (CI) and close coupling (CC) representations.
Journal ArticleDOI
On the validity of the ICFT R-matrix method: Fe xiv
TL;DR: In this article, Aggarwal et al. carried out an ICFT R-matrix calculation with the same 136-level configuration-interaction/close coupling (CI/CC) expansion adopted by Liang et al., and compared the results with their and with those of Liang and Srinivasan, which employed a much larger CI/CC expansion.

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.
