Different mechanisms that cause this phenomenon are investigated. Angle of polarization plane rotation for transition 6S_{1/2} -> 7S_{1/2} in cesium is estimated. The possibility to observe this effect in experiment is discussed.13 pages, 2 Postscript figures, misprint correctedHigh Energy Physics - Phenomenologytext
