康普顿散射中影响康普顿谱线位置的因素是十分复杂的,文章主要针对影响康普顿谱线位置的几个因素作了理论探讨,得出影响因素主要在于:电子具有初速度会增大散射波长的改变量;束缚能的存在要减小峰值波长的改变量;双光子散射和二次散射与谱线峰值位置的关系不大,二者对峰值波长的改变是不确定的、复杂的、在连续的范围内变化的。

After compared with the experiments,they have concluded that the double Compton scattering and the Compton scattering producing two photons can occurr possibly in Compton scattering.

从康普顿散射的基本原理出发,基于能量、动量守恒定律和相对论效应,首先讨论了康普顿散射中的二次散射,得出波长的改变量不仅与散射角有关,还与入射光子的波长(频率)有关;其次讨论了产生双光子的康普顿散射,由于这种散射的复杂性,只选取了两种特殊情形来讨论,得出散射光子的频率不仅与两个散射光子的散射角有关,还与入射光子频率有关,单一频率的入射光子发生双光子散射后,散射光子波长的改变还可能是连续变化的;康普顿散射实验说明二次散射和双光子散射的发生是可能的。
