Electron-impact ionization of C+excited states
TL;DR: In this article, both the time-dependent close-coupling and the timeindependent distorted-wave methods are used to calculate direct ionization cross sections for the 1s{sup 2}2s{ sup 2}3l configurations, including both direct and indirect excitation-autoionization contributions.

Spectroscopic diagnostics of low-ionized iron-peak elements. Electron-impact excitation of Ni3+ and photoionization of Ni2+
TL;DR: In this article, the authors employed modified versions of the parallel Dirac R-matrix codes, considering both electron-impact excitation of Ni$^{3+}$ and the photoionisation of both the ground and excited states of Ni€ 2+}$.

Electron collisional excitation of argon-like Ni XI using the Breit-Pauli R-matrix method
TL;DR: In this paper, the Breit-Pauli R-matrix was used to calculate the collision strengths for the transition from the ground state to the fine-structure levels of the 3s23p53d and 3s 23p63d configurations in Ni-XI.
Journal ArticleDOI
Photoionization of ground and excited levels of P II
TL;DR: In this article, the Breit-Pauli R-matrix (BPRM) method was used to calculate the photoionization cross section (σPI) of P II from ground and a large number of excited levels.

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.
