强外场中共振康普顿散射产生的增强高能光子

Enhanced, high energy photon production from resonant Compton scattering in a strong external field

A. Hartin

摘要:

从理论和唯象的角度考虑了电子/激光相互作用中的高阶强场效应。强场量子场论的Furry相互作用图是一个自洽的强场理论。在这个理论中,费米子被嵌入强激光场中,由此得到的Volkov波函数解对于强激光场是精确的。当这些沃尔科夫费米子与来自其他来源的单个光子相互作用时,当运动学允许虚费米子在壳层上时,跃迁概率在一系列共振中增强。提出了一个实验,其中,第一次,共振可以用来产生高能量的光子从相对论性电子在超过通常的机制的数量级的速率。

英文摘要:

A theoretical and phenomenological consideration is given to higher order, strong field effects in electron/laser interactions. A consistent strong field theory is the Furry interaction picture of intense field quantum field theory. In this theory, fermions are embedded in the strong laser field and the Volkov wavefunction solutions that result, are exact with respect to the strong field. When these Volkov fermions interact with individual photons from other sources, the transition probability is enhanced in a series of resonances when the kinematics allow the virtual fermion to go on-shell. An experiment is proposed in which, for the first time, resonances could be used to generate high energy photons from relativistic electrons at rates orders of magnitude in excess of usual mechanisms.
