摘 要：We have observed Bragg diffraction ofa Bose-Einstein condensate of sodium atoms by a moving,periodic,optical *** coherent process of Bragg diffraction prcduced a spitting of thecondensate with unidirectional momentum *** the momentum selectivity of the Braggprocess,we separated a condensate component with a momentrm Width narrower than that of theoriginal *** repeatedly pulsing the optical potential while the atoms were *** observed the trajectory of the split atomic wave packets in the confining magnetic potential.[S0031-9007(98)08316-1]
