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.

莫特自旋旋光仪的改进:一个被忽视的冗余
在莫特旋光仪中,通常通过使用四个相互成 90° 方位角放置的独立检测器收集散射电子来测量电子束沿两个垂直量化轴的自旋极化。然而,这四种强度并不是独立的量。将指出这种被忽视的冗余,并展示如何使用它以更好地设计、校准和操作莫特旋光仪。
