Abstract

The electric dipole intercombination decay of the $2 s 2 p$ ${}^{3}P_{1}^{0}$ level in the Be-like ion $C^{2 +}$ has been optically observed with ions circulating in a heavy-ion storage ring. The measured transition probability of $(102.94 \pm 0.14) s^{- 1}$ , corresponding to a lifetime of $(9.714 \pm 0.013)$ ms, is in good agreement with recent theoretical calculations. This precision measurement thus resolves the long-standing discrepancy of data from a radiofrequency ion trap experiment with theoretical predictions.
