摘要: 利用量子力学的Feynman路径积分表述形式对单电子双缝及多缝衍射的强度分布进行了详细推算.在远场近似下,得出了自由电子经狭缝衍射后在观测屏上的概率分布函数,结果与光波的Fraunhofer衍射一致,并对其物理图像进行了阐释.

Abstract: The quantum states of single electron through tow-slit or multi-slit and its probability distribution are calculated by using Feynman's path integrals. Based on our results, a clear physical description of this experiment is given to explain the diffraction state of single electron.

Key words: path integrals, diffraction state of electron, propagation function
