Abstract

A cylindrical cavity operated in the TE₀₁₃ mode which was used for excitation of the hyperfine transition in an optically pumped cesium beam spectrometer is discussed. In the configuration used, the atoms see the RF H-field, reverse its direction twice. The observed lineshapes show an interference structure similar to Ramsey interference. Theoretically derived lineshapes are in good agreement with the observations. A comparison is made between these lineshapes and corresponding Ramsey lineshapes. The effects of phase variations within the cavity are discussed briefly
