Abstract
The electric dipole intercombination decay of the level in the Be-like ion has been optically observed with ions circulating in a heavy-ion storage ring. The measured transition probability of , corresponding to a lifetime of 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.
