氢原子光谱同位素谱线位移实验的参数优化

摘要

讨论了氢原子光谱实验中狭缝宽度、采集次数和负高压对氢原子光谱同位素位移谱线的影响,优化了氢原子光谱同位素位移实验的工作参数,获得了清晰的氢原子同位素位移光谱.通过该实验让学生掌握实验中多参数优化的方法,有利于加深学生对光谱理论的理解,有利于提高学生分析问题解决问题的能力.%The influences of slit width, data-acquisition times, and negative high pressure on the isotope shift of H atom Spectroscopy were discussed, and experimental parameters were optimised, obtaining a clear isotope shifted spectra of H atom. By doing the experiment,students can master the optimization method of multiple parameters in the experiment, and understand the spectrospscopy theory deeply, which are beneficial for enhancing their problem-analyzing and -solving abilities.
