UK APAP R-matrix electron-impact excitation cross-sections for modelling laboratory and astrophysical plasma

We provide a large set of binned collision strengths and effective collision strengths for ions of theLi-, Be-, B-, C-, N-, O-, Ne-, Na-, and Mg-like sequences. They were calculated over a long period of time by theUK Atomic Process for Astrophysical Plasma (APAP) network,coordinated by the late Nigel Badnell, with funding from PPARC/STFC. AUTOSTRUCTURE and a suite of R-matrix codes, included in the package, were used. For several sequences, we have found problems in the published effective collision strengths, so the present values replace thepublished ones. The present data are fundamental for the modelling of laboratory and astrophysical plasma. The binned collision strengths are provided to model plasma where electrons are non-Maxwellian. Some details are provided in Del Zanna et al., 2025 Atoms, in a series of README files, and in the publications listed in the README files.
