摘要
结合德国PHYWE公司生产的Stern-Gerlach实验仪,简述了Stern-Gerlach实验的基本原理和内容设计;系统介绍了具体实验装置的组成部件和功能;考虑入射原子束的麦克斯韦速率分布后,理论分析了最终原子沉积束斑的形状;给出了典型的实验测量数据,讨论了测量曲线的偏差来源和进一步设想,评述了这一实验项目教学的意义.
Based on the SternGerlach experiment instrument produced by German PHYWE Com pany, the basic principle of SternGerlach experiment was presented briefly, and the design of the ex periment content was delivered. The components of the apparatus and their functions were introduced systematically. Considering the Maxwell distribution of the initial velocity of the incident atoms, the theoretical density distribution of the beam deposition was considered. Typical experimental data were showed. The deviation of the measured curves, further proposal and the instructive meaning of the experiment were discussed.
