摘要
教学实验中用NaI(Tl)单晶能谱仪测量γ射线强度与能量的关系,即γ能谱图,但不能测到康普顿效应中反冲电子的密度分布.本文介绍利用该仪器测定反冲电子密度分布,并与光子-电子的刚性小球作用模型所得结果进行比较.实验结果显示反冲电子密度随电子反冲角呈单调上升趋势,与理论结果符合较好.
The density distribution of recoil electrons in Compton effect is treated theoretically and measured experimentally, both results show that the density of recoil electrons exhibits a tendency of monotonically increasing with recoil angle.
