Benchmark comparisons for near-threshold electron-impact excitation of Ar metastable levels
TL;DR: In this article, a 41-state semi-relativistic R-matrix (close-coupling) approach was used to calculate the near-threshold electron-impact excitation of the metastable levels of Ar at low energies.

Excitation rate coefficients for fine-structure transitions in Al II
TL;DR: In this paper, the same authors presented a simulation of the collision strength for transitions among the lowest 20 fine-structure levels belonging to the,,, 3s3p, 3s 3d and 3s 4p configurations of Al II, over a wide electron temperature range of 5000 to 100 000 K.

Photoionization of potassiumlike transition-metal ions: Ti3+ to Fe7+
TL;DR: In this paper, photoionization cross-section calculations are performed on potassium-like transition metal ions (Ti{sup 3+}, V{sup 4+}, Cr{sup 5+}, Mn{sup 6+}, and Fe{sup 7+}) using both nonrelativistic coupling and relativistic (Breit-Pauli) R-matrix methods.
