Abstract
The 1s-2s energy interval in the muonium (mu(+)e(-)) atom has been measured by Doppler-free two-photon laser spectroscopy. A value of 2455528941.0(9.8 ) MHz has been obtained in good agreement with quantum electrodynamics (QED ). The muon-electron mass ratio can be extracted and is found to be 206.768 38(17). The measurement may also be interpreted as a determination of the m uon-electron charge ratio as -1- 1.1(2.1) . 10(-9). Corresponding measureme nts in deuterium using the same experimental setup confirmed the validity o f the applied analysis procedure.
