The use of basis splines and non-orthogonal orbitals in R-matrix calculations: application to Li photoionization
TL;DR: In this article, a new extended version of the R -matrix method for the calculation of continuum properties in which non-orthogonal orbitals are extensively used for describing both the target states and the R-matrix basis functions is presented.

Collision Strengths for Nebular (O iii) Optical and Infrared Lines
TL;DR: In this article, the Breit-Pauli relativistic terms were used to calculate the collision strengths of the nebular forbidden lines of doubly ionized oxygen ion, O2+, in an intermediate coupling scheme using the breit-pauli relatival terms as implemented in an R-matrix atomic scattering code.
