Figure 1.Diffraction patterns from a transmission grating [period = 100 nm] (curve A) of a beam composed of both sodium atoms (Na) and sodium dimers (Na2), and (curve B) of the same beam after the atoms have been removed with a deflecting laser beam, leaving only Na2 molecules.

Figure 3.Phase shift of the interference pattern of a separated-beam atom interferometer as a function of voltage applied to the left or right side of the interaction region. In either case, the magnitude of the phase shift shows a quadratic increase with voltage.
