Oscillator Strengths and Electron Collision Rates for Fine-Structure Transitions in O II
TL;DR: In this paper, the impact excitation collision strength for the fine-structure transitions between the lowest 13 levels of the 2s22p3, 2s2p4, and 2s 22p23s configurations was calculated using a 62-level Breit-Pauli R-matrix approach with orthogonal radial functions and a 47-level B-spline basis has been used for the description of continuum functions, and no orthogonality constraint has been imposed between the continuum functions and the valence atomic orbitals.
