论文摘要
我们提出了仅基于两光子相互作用的自旋依赖性kapitza-dirac散射的可能性。相互作用方案的灵感来自康普顿散射过程，为此，我们明确地显示了在静光波中电子衍射过程的自旋动力学的数学对应关系。自旋效应的优点是它已经出现在带有任意低场幅度的Bragg散射设置中，为此，我们估计了在可用的X射线自由电子激光器设备上逼真的实验设置中的衍射率。
We present the possibility of spin-dependent Kapitza-Dirac scattering based on a two-photon interaction only. The interaction scheme is inspired from a Compton scattering process, for which we explicitly show the mathematical correspondence to the spin-dynamics of an electron diffraction process in a standing light wave. The spin effect has the advantage that it already appears in a Bragg scattering setup with arbitrary low field amplitudes, for which we have estimated the diffraction count rate in a realistic experimental setup at available X-ray free-electron laser facilities.
