Title: Measurement of the muonium 1S-2S transition frequency

Abstract

Resonant ionization spectroscopy has been employed for measuring the 1{sup 2}S1/2-2{sup 2}S1/2 frequency difference in the hydrogen-like muonium atom to 2 455 529 002(33)(46) MHz. The 1S-2S two-photon transition was induced Doppler-free using two counter-propagating laser beams. The 2S state was photo-ionized by a third photon from the same laser field. The measurement agrees with QED theory within two standard deviations. The mass of the positive muon can be extracted from the isotope shifts in this transition to hydrogen and deuterium to 105.658 80(29)(43) MeV/c{sup 2}.

  • The 1S/sub 1/2/-2S/sub 1/2/ transition frequency in atomic hydrogen has been interferometrically measured by comparison with a reference line in /sup 130/Te/sub 2/ by Doppler-free two-photon laser spectroscopy. The measured 1S/sub 1/2/-2S/sub 1/2/ transition frequency of 2 466 061 397(25) MHz is in good agreement with the theoretical predictions of Erickson modified to take account of recent measurements of the Rydberg constant. This measurement can be used to deduce a value for the ground-state Lamb shift and gives the result of 8182(25) MHz which compares with a value of 8173.248(81) MHz predicted by Erickson.
  • We have measured the 1S-2S transition frequency in atomic hydrogen with a precision of 7 parts in 10/sup 10/ by continuous-wave Doppler-free two-photon spectroscopy. We employ cavity-enhanced multimilliwatt radiation near 243 nm produced by sum-frequency generation, and we observe the 1S-2S transition in a low-pressure hydrogen-helium cell with a resolution of 3 parts in 10/sup 9/. For a frequency comparison we detect an optical heterodyne signal at the difference frequency between the 243-nm light used to excite the 1S-2S transition and the second harmonic of a reference laser locked to an interferometrically calibrated /sup 130/Te/sub 2/ absorption line near 486more » nm. After determining systematic corrections due to the pressure shift of the F = 1 hyperfine component in a 0.7 vol. % hydrogen--99.3 vol. % helium gaseous mixture, we obtain the energy-level separation f(1S-2S) = 2 466 061 413.2(18) MHz. Choosing a value of the Rydberg constant measured independently by high-resolution spectroscopy of the hydrogen Balmer-..beta.. transition, we find the hydrogen ground-state Lamb shift to be f/sub LS/(1S) = 8173.9(19) MHz, in good agreement with the theoretical value of 8172.89(9) MHz.« less
  • We present evidence for the excitation of the two-photon Doppler-free 1S-2S transition in muonium. Thermal muonium atoms were produced in vacuum by a 27.5-MeV/c pulsed positive-muon beam incident on a powdered SiO/sub 2/ target. Transitions were induced by the light from a frequency-doubled pulsed dye laser and were detected by photoionization of the 2S state. The 1S(F = 1)..-->..2S(F = 1) transition frequency is within 300 MHz of the QED prediction.
