【 摘 要 】

We have measured the radiative lifetime of the1S0metastable level in Kr2+using an electrostatic ion trap. The obtained lifetime was 17.4 ± 0.4 ms. Comparing with the previous results, our value is consistent with the theoretical predictions, but inconsistent with the experimental results even considering their errors.
