An R -matrix with pseudo-states calculation of electron-impact excitation in C 2 +
TL;DR: In this paper, an R-matrix with pseudo-state (RMPS) calculation of electron-impact excitation in C2+ was performed, and the collision strengths and effective collision strengths were determined for excitation between the lowest 24 terms, including all those arising from 2s3l and 2s4l configurations.
