Atomic Electron Motion for Möller Polarimetry in a Double-Arm Mode
Andrei Afanasev, Alexander Glamazdin
Abstract
We analyse an effect of electron Fermi motion at atomic shells on the accuracy of electron beam polarization measurements with a Möller polarimeter operating in a double--arm mode. It is demonstrated that the effect can result in either increase or decrease of the measured polarization depending on the detector positions. The effect is simulated for the Möller polarimeter to be installed at CEBAF Hall A.
