论文摘要
已经计算了针对$ e^+\，e^ - \至γ\，γ$反应的差异横截面和一些极化可观察到的，这些反应考虑了重型激发电子的贡献和一般形式的$ e \，e \，e \，γ\，γ$接触相互作用。对于两种光束都有任意极化的情况，计算自旋相关系数。如果仅一个光束极化，则估计所谓的左右不对称性。给出了激发电子对差分横截面的贡献的数值估计，以及对电子束能量和激发电子质量的各种值的自旋相关系数。
The differential cross section and some polarization observables have been calculated for the $e^+\,e^-\to γ\,γ$ reaction taking into account the contribution of the heavy excited electron and the general form $e\,e\,γ\,γ$ contact interaction. The spin correlation coefficients are calculated for the case when both beams have arbitrary polarization. The so called left-right asymmetry is estimated if only one beam is polarized. Numerical estimations are given for the excited electron contribution to the differential cross section and spin correlation coefficients for various values of the electron beam energy and excited electron mass.
