Abstract
In a quest for benchmarking transition rate data on electric-dipole () forbidden transitions to be used in collisional-radiative models of plasma spectra, the radiative decay rates of the metastable levels , , and 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 Si, P, P, P, S, and S obtained here complete the isoelectronic sequence data sets for these four metastable levels in all three elements.
