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 2s2p^{3 5}S ₂ level in O²⁺, 530(25) ms and 304(3) ms for the 2s² 2p^{2 1}S₀ level in O²⁺ and F³⁺, respectively, and 5.36(10) ms and 2.14(2) ms for the 2s²2p^{3 2}P 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.
