摘要
为了澄清对康普顿散射过程中存在的误解,增加对康普顿散射的直观理解,首先辨析了光电效应和康普顿散射实验的异同,随后对康普顿碰撞的理论进行了详细推导,并基于MATLAB对康普顿散射进行了模拟.研究表明:康普顿散射波长改变量的增长率和反冲电子获得的能量以及动量增长率均随散射角的增大而增加.但反冲电子的动量增长率比能量增长率随角度的变化表现得更为明显和剧烈.在散射角一定的情况下,反冲电子的动量和能量增长率均随入射光波长的减小而增加.最后讨论了康普顿散射的物理意义.
Abstract
In order to clarify the misunderstandings of Compton scattering process and increase the intuitive understanding of it,the differences and similarities between the photoelectric effect and the Compton scattering experiment is first analyzed,then the theory of Compton collision is derived in detail,and the Compton scattering is simulated based on MATLAB.The study results show that:with the increase of scattering angle,the growth rate of Compton scattering wavelength change and the growth rate of recoil electron's energy and momentum both show an upward trend.However,compared with the growth rate of energy,the growth rate of recoil electron's momentum is more significant and dramatic in the aspect of angle change.At a given scattering angle,the growth rate of recoil electron's momentum and energy will also increase with the decrease of incident light wavelength.Finally,the physical significance of Compton scattering is discussed.
