我们给出了用惰性核上方准两电子原子的相对论收敛紧耦合方法计算锌和汞原子弹性电子散射的自旋不对称参数(谢尔曼函数)。在各种能量范围内，汞的计算结果与实验结果非常一致。同样，对于锌，我们发现在能量低于9.0 eV的情况下，理论和实验之间有很好的一致性。然而，在11.0 eV时，理论和实验之间存在差异，很可能是由于核心电子的共振激发。
We present spin-asymmetry parameters (Sherman functions) for elastic electron scattering on zinc and mercury atoms calculated using the relativistic convergent close-coupling method for quasi-two-electron atoms above an inert core. The results for mercury are in excellent agreement with experiment across a wide range of energies. Similarly for zinc, we find excellent agreement between theory and experiment for energies below 9.0 eV. However, at 11.0 eV there is a discrepancy between theory and experiment, most likely due to a resonance excitation of a core electron.
