Phys. Rev. Lett. 56, 827–830 (1986)Diffraction of atoms by light: The near-resonant Kapitza-Dirac effectReceived 28 October 1985; published in the issue dated 24 February 1986 We have observed the Kapitza-Dirac effect in the scattering of sodium atoms by a nearly resonant standing-wave laser field. The data clearly show diffraction peaks of the atomic momentum transfer at even multiples of the photon momentum. Theoretical predictions for an off-resonant, adiabatic interaction with a two-state system are in reasonable agreement with the data. © 1986 The American Physical Society URL:
