运用原子非弹性碰撞模型来测量F-H曲线峰谷间距随峰谷数的线性关系,研究温度对电子平均自由程的影响,并尝试探讨一种较为准确的测量原子第一激发能的实验方法.
Using the model of inelastic collisions, the linear relation between the peak (or valley) separations in the Franck-Hertz curve and the corresponding number of peaks (or valleys) is obtained, and the influence of temperature on the mean free path of the electrons is found. The method of higher precision for the measurement the lowest excitation energy of atom is discussed.
