Abstract

Rates of an intercombination transition and of several electric-dipole forbidden transitions between the levels of the ground state in C-like ions of O and F and in N-like ions of S have been measured optically at a heavy-ion storage ring. The lifetime results, 1.250(13) ms for the 2s2p3 5S 2 level in O2+, 530(25) ms and 304(3) ms for the 2s2 2p2 1S0 level in O2+ and F3+, respectively, and 5.36(10) ms and 2.14(2) ms for the 2s22p3 2P 1/2,3/2 levels of S9+, agree with only some of the theoretical predictions, while they have a lower estimated uncertainty then all of them.
