The Properties of the Differential Scattering Section Based onthe Multi-photon Nonlinear Compton Scattering in a Strong Magnetic Field

应用电子与光子非弹性碰撞模型,分析、计算了磁逆多光子非线性Compton微分散射截面的特性。结果表明:该微分散射截面随与电子同时作用光子数及电子与光子碰撞非弹性成分的增大而减小,散射光子的频率逐渐趋于共振频率,但不具有共振性;当电子被光场俘获时,磁逆多光子非线性Compton微分散射截面为一恒定值。

The properties of the differential scattering section based on the inverse multi-photon nonlinear Compton scattering in strong magnetic field is studied using an inelastic collision model of electron with photons. An expression for the differential scattering section between a relativistic electron and photons in derived. It is shown the differential scattering section of scattered photons is reduced by the electron absorption photons number n at the same time and collision no elastic ξ increase between electron and photons, and the frequency of scattered photons slowly approaches resonance frequency, but it is not this frequency; In extra-intense stationary laser field, when multi-photon nonlinear Compton scattering is token between relativistic electron and photons, and electron is captured by the laser field ,the differential scattering section is a constant.
