摘要

If circularly polarized light is spread along the direction of the constant magnetic field H_o, then, applying the resonance magnetic field, perpendicular to H_o, it is possible to observe this magnetic resonance of optically spin- polarized atoms. It has been shown that the signal of magnetic resonance acquires the intricate shape: an appearance of a gap in the centre of resonance curve and correspondingly two side maxima when the orientation and alignment give the comparable contributions in it. It has been determined the dependence on a (the ratio of the contributions to the signal due to orientation and alignment) for the following variables: the splitting of the resonance curve; the limit value of the resonance magnetic field at which the gap appears in the center of the line; the ratio of the signal in the center of the resonance line to that in the maxima. The effect take place for the states with angular momentum J > S.
