描述了一种新方法，可以对电子自旋偏振分析仪进行精确的绝对校准。它基于测量自旋轨道引起的散射不对称性以及弹性电子散射中散射电子的同步偏振分析。展示了如何轻松确定经典高能莫特探测器的有效谢尔曼函数，使其误差在 ±2% 以内。该方法也适用于其他类型的电子自旋偏振探测器。
A new method is described which allows the accurate absolute calibration of an electron‐spin polarization analyzer. It is based on measuring spin–orbit‐induced scattering asymmetries and simultaneous polarization analysis of the scattered electrons in elastic electron scattering. It is shown how the effective Sherman function of a classical high‐energy Mott detector can be determined easily to within better than ±2%. The method is applicable to other types of electron‐spin polarization detectors as well.
