摘　　要：应用电子与多光子集团非弹性Compton散射模型,分析、计算了磁逆多光子非线性Compton散射的电子加速,结果表明,散射前做Landau圆轨道运动的电子并非是热电子,而是处于激发态的电子。当耦合光的频率与处于激发态电子的频率相等时,能发生磁逆多光子非线性Compton散射,放出高γ射线,但产生高γ射线的几率要比产生低γ射线的几率小。若电子被光场俘获,电子可从激光场中获得巨大的加速能量。The electron acceleration based on the inverse multi-photon nonlinear Compton scattering in the extra-intense stationary laser field is studied by using an inelastic collision model of electron with a multiphoton group. The results show that the Landau course electron before the inverse multi-photon nonlinear Compton scattering in the extra-intense stationary laser field are not hot electron, but electron in an excited state. When the frequency of the coupling optical field equals the frequency of the electron in an excited state, the inverse multi-photon nonlinear Compton scattering take place and put out the high γ-ray. But, the probability of the high γ-ray is less than that of the low γ-ray. When the electron is captured by the extra-intense stationary laser field, a great acceleration energy can be obtained by the electron.
