Oscillations in the number of transitions in a molecular beam that passes through two separated radio-frequency fields, as a function of L/v, where L is the separation of the field and v is the speed of the beam.

A magnetic-field inhomogeneity will shift the Ramsey fringes with respect to the underlying Rabi pedestal.
Stepping the synthesizer frequency between measurement cycles produces a set of Ramsey fringes.
This technique relies on the fact that the shift in the Rabi pedestal part of the line shape is large compared to the shift in the Ramsey fringe part of the line shape.
