In Mott polarimeters, the measurement of the spin polarization of an electron beam along two perpendicular quantization axes is commonly performed by collecting scattered electrons with four independent detectors placed azimuthally at 90° from each other. However, the four intensities are not independent quantities. This overlooked redundancy will be pointed out, and it will be shown how to use it in order to better design, calibrate, and operate Mott polarimeters.
在莫特偏振仪中，通常通过使用四个相互独立且在方位角上彼此间隔90°放置的探测器收集散射电子，来测量沿两个相互垂直的量化轴的电子束自旋极化。然而，这四个强度并非独立量。将指出这种被忽视的冗余性，并展示如何利用它来更好地设计、校准和操作莫特偏振仪。
