周期磁场中的相对论电子与光辐射的能量交换

基于相对论电子在周期磁场和光辐射场作用下的运动方程,讨论了相对论电子与光辐射之间的有效的能量交换。结果表明,相对论电子与光辐射只有在满足共振条件的频率上发生能量交换。光辐射是被相对论电子放大还是成为加速电子运动的动力,取决于两者的位相关系。

On the energy exchange between relativistic electrons in periodic magnetic field and light radiation

The energy exchange between relativistic electrons (r.e.) and light radiation are discussed on the basis of the movement equations for the interaction of relativistic electrons with periodic field and the radiation field. It is shown that effective energy exchange can take place only at the frequeney satisfying the resonance condition. Depending on their phase of light relation, radiation can be amplified by the relativistic electrons or becomes the force accelerating the electrons.
