Ramsey fringes have been produced by stimulated resonance Raman scattering between ground-state hyperfine levels at two separated points along a sodium atomic beam. Observed transit time broadening was 1. 3 kHz (FWHM), as expected for the 30 cm separation of the two regions. The requisite two copropagating laser fields, omega //p (pump) and omega **s (stokes), were obtained by frequency shifting a portion of our tunable dye laser output using an acousto-optical modulator (AOM) such that omega //p minus omega **s equaled the hyperfine transition frequency. The linear polarizations of omega //p and omega **s were perpendicular to each other. The initial and final states were the F equals 1 and F equals 2 hyperfine levels of the 3**2s// one-half ground state. The resonant intermediate level was the 3**2p// one-half (F prime equals 2) state. A magnetic holding field (about 300 mG), parallel to the laser beams, was used to separate the magnetic sublevel.
