The authors 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 {le} Z {le} 36). Special attention has been paid to provide a complete tabulation of all electric-dipole (E1) allowed transitions from levels of the 3s3p{sup 3} and 3s{sup 2}3p3d excited configurations to those of the 3s{sup 2}3p{sup 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. They further investigate the decay of the 3s{sup 2}3p3dJ = 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, they compare the results with experiment and with previous computations.
