摘要: 使用量子力学中Feynman的路径积分方法,导出了重力场中原子经单缝、双缝及多缝衍射后的量子态及其概率分布.在一定近似条件下,证明了干涉条纹的移动与重力加速度有关,而条纹间隔与重力加速度无关.

关键词: 重力场, 原子衍射态, 概率分布

Abstract: The diffraction state and its probability distribution for an atom passing through a single slit, double-slit or N-slit in the gravitational field is derived using Feynman'path integral approach in the quantum mechanics. It shows that the fringe shift is dependent on the acceleration of gravity in an approximate conditions, but the fringe spacing is not dependent on it.

Key words: gravitational field, diffraction state of an atom, probability distribution
