摘要
We have studied atomic diffraction at normal incidence from an evanescent standing wave with high resolution using velocity-selective Raman transitions. We have observed up to three resolved orders of diffraction, which are well accounted for using scalar diffraction theory. In our experiment the transverse coherence length of the source is greater than the period of the diffraction grating.
