 Abstract: In a quest for benchmarking transition rate data on electric-dipole (E1) forbidden transitions to be used in collisional-radiative models of plasma spectra, the radiative decay rates of the metastable levels 2s22p2 1 D2, 2s22p3 2 P1/2,3/2o, and 2s22p4 1 D2 in C-, N-, and O-like ions, respectively, have been measured for the elements Si, P, and S. Results with uncertainties mostly well below 1% are obtained using ions circulating in a storage ring. Precision results for Si7+, P7+, P8+, P9+, S8+, and S10+ obtained here complete the isoelectronic sequence data sets for these four metastable levels in all three elements.
