B. Phase DifferenceErrors If the two oscillating fields of the Ramsey excitation structure are in phase, a maximum beam signal is observed at the resonance frequency. If the two fields are 180" out of phase, a minimum signal is observed at the resonance frequency. The central peak is shifted approximately a fringe width as the phase difference is shifted from 0" to 180". 7 cps which is significant. For the purpose of reducing the phase difference between the two fields, it was found quite effective to pass the beam through the two ends of a single rectangular resonant cavity electroformed in the shape of a U .

In the event that there is a component of the radiation field in the z-direction-contrary to the assumption made in writing Eq. (62)-the matrix elements of J. are necessary in calculating the transition probability. The (F = 4, mF = 0) t) ( P = 3, mF = 0) transition in cesium is a case in point. Torrey has given a useful approximate evaluation of b for general values of the C field intensity (29). r-transitions, 43 ATOMIC BEAM FREQUENCY STANDARDS where H, is the component of the radiation field perpendicular to Ho, and ( pare , the ~ ~ magnetic moments of the states F, mF.

20. NBS-I atomic beam frequency standard. 48 RICHARD C. MOCKLER errors do limit the accuracy of cesium frequency standards. Beam devices with 300 cps line widths have demonstrated greater accuracy than those devices with much narrower resonances. As time progresses it is expected that longer machines will more closely approach their ideal capabilities. Certain fixed parameters and effects that determine absolute frequency may be measured by auxilliary experiments. The effects that are now considered to contribute the greatest inaccuracies are : (a) The magnitude and nonuniformity of the C field, including variations in the magnitude over long periods, (b) A phase difference between the two oscillating field regions, and (c) A lack of purity of the electromagnetic field exciting the atomic transition.
