Relativistic R-Matrix Close-Coupling Calculations for Photoionization of Si-Like Ni XV
TL;DR: In this article, a relativistic close-coupling photoionization calculation of Ni XV using the Breit-Pauli R-matrix method was presented to obtain photoionisation cross section of Ni XVI from the ground state 3s 23p 2(3 P 0) and the lowest four 3s23p 2 (3 P 1,2, 1 D 2, 1 S 0) excited states.

Electron-impact excitation of Co{sup 2+}
TL;DR: In this article, the authors used distorted-wave approximation to calculate the electron-impact excitation cross sections and Maxwellian-averaged rate coefficients from the ground 3d{sup 7}thinsp{sup 4}F to the ground Co{sup 2+} in close coupling with 8 and 27 terms.

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.
