Show affiliationsWe present results for the electron-impact excitation of F-like ions from Ne+ to Kr27+ using an R-matrix approach where the intermediate-coupling frame transformation method has been used to obtain level-resolved collision strengths. For each calculation, the target has been expanded using 87 terms (195 levels) with the following configuration basis: 2s2 2p5, 2s 2p6, 2s2 2p4 3l, 2s 2p5 3l and 2s2 2p4 4l. Comparisons are made with previous R-matrix calculations for the fine-structure transition over the whole sequence and other, more extensive, calculations on Ne+ and Fe17+. We examine iso-electronic trends of both low- and high-temperature effective collision strengths. This complete, self-consistent set of radiative and collision data is archived in multiple databases.
