Measurement of the 1s-2s energy interval in muonium
V. Meyer, S. N. Bagayev, P. E. G. Baird +26
The 1s-2s interval has been measured in the muonium ({}) atom by Doppler-free two-photon laser spectroscopy. The frequency separation of the states was determined to be 2 4…
New Bounds from Searching for Muonium to Antimuonium Conversion
L. Willmann, P. V. Schmidt, H. P. Wirtz +26
A new upper limit for the probability of spontaneous muonium to antimuonium conversion was established at (90%C.L.) in 0.1~T magnetic f…
Increased Sensitivity to Possible Muonium to Antimuonium Conversion
V. Meyer, A. Grossmann, K. Jungmann +23
A new experimental search for muonium-antimuonium conversion was conducted at the Paul Scherrer Institute, Villigen, Switzerland. The preliminary analysis yielded one event fulfill…
Results from Searching for Muonium to Antimuonium Conversion
K. Jungmann, A. Grossmann, J. Merkel +23
A new result from searching for muonium to antimuonium conversion is reported which sets an upper limit on the coupling constant in an assumed type interaction…
