EBIT trapping program
The LLNL electron beam ion trap provides the world's only source of stationary highly charged ions up to bare U. This unique capability makes many new atomic and nuclear physics experiments possible.
Laser spectroscopy of the (1s(2)2s2p) P-3(0)-P-3(1) level splitting in Be-like krypton
15th International Conference on the Physics of Highly Charged Ions, HCI2010, Fudan Univ, Shanghai, PEOPLES R CHINA, AUG 29-SEP 03, 2010; International audience; Heavy few-electron ions, such as He-, Li- and Be-like ions, are ideal atomic systems to study the effects of correlation, relativity and quantum electrodynamics. Very recently, theoretical and experimental studies of these species achieved a considerable improvement in accuracy. Be-like ions are interesting because their first excited state, i.e. (1s(2)2s2p) P-3(0), has an almost infinite lifetime (tau(0)) in the absence of nuclear spin (I), as it can only decay by a two-photon E1M1 transition to the (1s(2)2s(2)) S-1(0) ground stat…
