用纵向极化电子束研究了原子场韧致辐射。在光子高能尖端区测量了电子自旋初始取向与光子极化角之间的相关性。在时间反演中，这对应于一种迄今未观察到的现象，即用线偏振光子光电离非极化原子产生纵向极化电子。结果证实了辐射复合的完全相对论计算，并提出了一种新的电子束偏振测量方法。
Atomic-field bremsstrahlung has been studied with a longitudinally polarized electron beam. The correlation between the initial orientation of the electron spin and the angle of photon polarization has been measured at the photon high energy tip region. In the time reversal this corresponds to a so-far unobserved phenomenon of production of longitudinally polarized electrons by photoionization of unpolarized atoms with linearly polarized photons. The results confirm the fully relativistic calculations for radiative recombination and suggest a new method for electron beam polarimetry.
