Abstract / Description:The lifetime of the Ar13+ 1s22s22p 2P3/2o metastable level was determined at the Heidelberg Electron Beam Ion Trap to be 9.573(4)(5) ms(stat)(syst). The accuracy level of one per thousand makes this measurement sensitive to quantum electrodynamic effects like the electron anomalous magnetic moment (EAMM) and to relativistic electron-electron correlation effects like the frequency-dependent Breit interaction. Theoretical predictions, adjusted for the EAMM, cluster about a lifetime that is approximately 3sigma shorter than our experimental result.
