We present theoretical excitation energies and lifetimes for the 27 low-lying levels of silicon-like ions of S, Ar, Ca, Ti, Fe, Zn, and Kr (16 ≤Z≤ 36). Special attention has been paid to provide a complete tabulation of all electric-dipole (E1) allowed transitions from levels of the 3s3p 3 and 3s 2 3p3dexcited configurations to those of the 3s 2 3p 2 ground-state configuration, including all weak and intercombination transitions. Large-scale multiconfiguration Dirac–Fock wave functions are applied to compute transition energies and probabilities. We further investigate the decay of the 3s 2 3p3d J= 4 level which is connected to the ground-state configuration only via forbidden M2 transitions but otherwise mainly decays via M1 to lower-lying levels of the same parity. For a few selected data, we compare our results with experiment and with previous computations.
