Summary
A novel method for measuring hyperfine Zeeman transitions in muonium,i.e. « Ramsey resonance » in high field, is described both theoretically and practically. Various potential sources of systematic errors are exhaustively discussed. Data taken at 30 atm krypton buffer gas pressure are presented. They agree with the most accurate previous high-field results, and provide evidence for the so-calledg j shift in muonium.
Riassunto
Si descrive sia teoricamente che praticamente un nuovo metodo per misurare le transizioni iperfine di Zeeman nel muonio, cioè la «risonanza di Ramsey» nel campo forte. Si discutono in modo esauriente numerose sorgenti potenziali di errori sistematici. Si presentano dati presi da 30 atm della pressione del gas tampone di krypton. Essi sono in accordo con i precedenti più accurati risultati del campo forte, e forniscono prove per il cosiddetto spostamentog j nel muonio.
Реэюме
Теоретически и зкспериментально описывается новый метод иэме-рения сверхтонких эеемановских переходов в мюонии, т.е. «реэонанс Рамсея» в интенсивном поле. Обсуждаются раэличные потенциальные источники система-тических ощибок. Приводятся данные, полученные при давлении буфферного гаэа криптона в 30 атм. Полученные реэультаты согласуются с более точными предыду-шими реэультатами в интенсивном поле и подтверждают так наэываемый «g j» сдвиг в мюонии.

After this work was completed, the uncertainty in the WQED value ofα (based on 2e/h from the Josephson effect) has been reduced to 0.2 ppm (P. T. Olsen andE. R. Williams: inProceedings of the Fifth International Conference on Atomic Masses and Fundamental Constants, edited byJ. H. Sanders andA. H. Wapstra (New York, N. Y., 1975)) by a redetermination of the gyromagnetic ratio of the proton. This dramatic improvement by no means reduces the usefulness of further\(\mu _\mu \) determinations. The motivation will simply shift to that of a more stringent verification of QED corrections to the Fermi formula.

In ref. (3) there is an approximate factor-two discrepancy between the single-pulse peak signal height displayed in fig. 14 and the peak double-pulse height of fig. 16. We resolve this by noting that the signaldefinition used for the data of fig. 14 isS=(N on−N off)/N off, which gives signals a factor two larger than the stated signal definition (eq. (26) of ref. (3)),i.e. S=(N on −N off)/(N on+N off).
