Journal ArticleDOI
Dirac R-matrix with pseudo-states
TL;DR: In this article, the Dirac R-matrix with pseudo-state (DRMPS) method for electron and photon collisions with arbitrary atoms and ions was described, and implemented quite generally within the general relativistic atomic structure package (GRASP) specifically GRASP0.

Quantum defect theory with deeply closed channels
T. W. Gorczyca,N. R. Badnell +1 more
TL;DR: In this paper, the validity and practicality of using multi-channel quantum defect theory (MQDT) to treat electron-ion collision problems for cases where some channel solutions propagate with extremely negative, classically forbidden, energies were discussed.

Energy levels, radiative rates, and electron impact excitation rates for transitions in Li-like ions with 12≤Z≤20
TL;DR: In this paper, a general-purpose relativistic atomic structure package is adopted for calculating energy levels and radiative rates, while for determining the collision strengths and subsequently the excitation rates, the Dirac atomic R-matrix code is used.

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.
