Evidence of coherence effects has been observed in the Zeeman sublevels by means of nonlinear level crossing in a metastable Ca beam with resonance width 3 orders of magnitude less than the radiative linewidth of the investigated transitions. By using two separate traveling waves, Ramsey-like fringes have been observed. The final measured are determined by the transit time, are weakly dependent on the magnetic-field inhomogeneities, and are widths independent of the natural width of the optical transitions and the laser bandwidth.
