It is demonstrated that the effect can result in either {\it increase} or {\it 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.LaTeX, 7 pages, 4 postscript figuresHigh Energy Physics - ExperimentAtomic PhysicsNuclear Experimenttext
