激光-电子非线性康普顿散射中电子的特性研究

RESEARCH ON THE ELECTRONIC PROPERTIES OF LASER- ELECTRON COMPTON SCATTERING

利用单粒子理论和电子与光子非弹性碰撞模型，对激光一电子非线性康普顿散射的电子的速度进行了研究．通过理论推导得出了电子的能量变化因子的表达式，同时讨论了电子与光子碰撞后的速度．结果表明，电子与光子碰撞后的速度不仅与碰撞之前电子的速度和n光子集团的频率有关，还与电子与n光子集团入射方向与散射方向间的夹角和光子的散射角有关．

Single particle theory and the mode of electronic and photonic elastic are adopted. Electronic speed in laser- electronic nonlinear Compton scattering is stcldied. Through theoretical derivation and discussion, we get the electronic speed after the collision between electronic and photonic. It shows that electronic speed after the collision between electronic and photonic is not only related to the electronic speed before the collision and the N -photon group freqrency, but depends on the angle between electronic and N -Photon group which is before and after their collision, and the N - photon group scattering angle.
