摘要：
The electric dipole intercombination decay of the 2s2p P-3(1)0 level in the Be-like ion C2+ has been optically observed with ions circulating in a heavy-ion storage ring. The measured transition probability of (102.94 +/- 0.14) s(-1), corresponding to a lifetime of (9.714 +/- 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.
