Measurement of the 1s-2s energy interval in muonium
نویسندگان
چکیده
The 1s-2s interval has been measured in the muonium (&mgr;(+)e(-)) atom by Doppler-free two-photon pulsed laser spectroscopy. The frequency separation of the states was determined to be 2 455 528 941.0(9.8) MHz, in good agreement with quantum electrodynamics. The result may be interpreted as a measurement of the muon-electron charge ratio as -1-1.1(2.1)x10(-9). We expect significantly higher accuracy at future high flux muon sources and from cw laser technology.

The 1s-2s interval has been measured in the muonium (μ+e−) atom by Doppler-free two-photon laser spectroscopy. The frequency separation of the states was determined to be 2 455 528 941.0(9.8) MHz in good agreement with quantum electrodynamics. The muon-electron mass ratio can be extracted and is found to be 206.768 38(17). The result may be interpreted as measurement of the muon-electron charge...

متن کاملMuonium Spectroscopy
The electromagnetic interactions of electrons and muons can be described to very high accuracy within the framework of standard theory, in particular within the hydrogen-like muonium atom. Therefore precision measurements allow to test basic interactions in physics and to search for yet unknown forces. Accurate values for fundamental constants can be obtained. Results from experiments on the gr...
متن کاملPrecision Study of Hyperfine Structure in Simple Atoms
We consider the most accurate tests of bound state QED theory of the hyperfine splitting in two-body atoms related to the HFS interval of the 1s state in muonium and positronium and the 2s state in hydrogen, deuterium and the helium-3 ion. We summarize their QED theory and pay special attention to involved effects of strong interactions and to recent optical measurements of the 2s HFS interval ...
متن کاملThe Lamb Shift of Hydrogen and Low-energy Tests of Qed
Leading logarithmic corrections to the difference of Lamb shifts of s-states EL(1s) − 8EL(2s) and to the life time of 2p1/2 state are considered. The result of Sokolov and Yakovlev for the Lamb splitting of 2s1/2 and 2p1/2 is reevaluated and our new value is 1057.8576(21) MHz. Using value of EL(1s)− 8EL(2s) = -187.237(8) MHz, obtained here, a new value of the Hydrogen and Deuterium ground state...
