Show affiliationsWe have determined effective collision strengths for fine-structure transitions among the 2s22p2 and 2s2p3 configurations of seven ions in the C I isoelectronic sequence, by interpolating or extrapolating from data calculated by the R-matrix method for the C-like species Si IX, Ca XV and Fe XXI. We present the results as coefficients to polynomial fits which may be used to estimate the effective collision strengths to an accuracy of ±20%.
