【摘要】 研究在短时原子与场相互作用极限下窄原子束在共振驻波场中的运动．原子的平动和内部运动按量子力学处理，而电磁场则处理为经典场．结果表明，原子的动量几率密度由两种动量分布组成．在典型的情况下，原子束的偏转达到２×１０－３ｍｍ数量级更多还原

【Abstract】 We study the motion of a narrow atomic beam in a resonant standing electromagnetic wave in the limit of short atom field interaction time.The translational and internal motions of the atom are treated quantum mechanically, while the field is treated classically.It is shown that the momentum probability density consists of two momentum distributions.The atomic deflections of order 2×10 -3 mm are achieved for a typical case.更多还原
