We present collision strengths and rate coefficients for electron-impact excitation of He-like ions (S 14+ , Ar 16+ , Ca 18+ ) using the Dirac Atomic R-matrix Code, which has been developed by Norrington and Grant [J. Phys. B: At. Mol. Opt. Phys. 20 (1987) 4869]. The lowest 45 target levels are incl
