- backward scattered electron 反向散射电子, 后向散射电子
- The pulse width of the backward scattered radiation decreases with the increase of the electron’s initial energy, and the collimation of the scattered radiation becomes better. 短脉冲激光条件下得到的后向散射光的频率上移与长脉冲激光条件下得到的后向散射光的频率上移是完全一致的,同时发现随着入射电子初始能量的增加,散射光的准直性越来越好,后向散射光脉冲的脉宽越来越短。
