摘要
当辐射为康普顿散射时,由于靶电子的运动,散射光谱应为多普勒增宽。分析这一增宽线形——康普顿轮廓,就可确定出散射体中电子动量密度的分布。从量子系统而言,电子的动量密度分布当然也可用动量空间中的波函数来确定,但动量空间中的波动方程却是一个难以处理的积分问题。
When radiation is in the way of Compton-scattering, the scat- tering beam is Doppler-broadened because of the motion of the target electrons. An analysis of this broadened lineshape—the Compton profile, can determine the distribution of the electron momentum in the scat- terer. In the case of the quantum system,the distribution of the electron mom entum can be determined with the wavefunctions in momentum space, but wave equation in momentum space is difficult to deal with integrated problems.
