Majorana atomic transition research in H-maser´s magnetic state selection region

For efficient performance of a single-state selection system when using Majorana method, it´s extremely important to know how eventual angle of rotation for atom´s spin depends on a total magnetic field in a region between selection magnets. As it was shown in previous work, the angle of rotation for spinor F = 1 greatly depends on a transverse (in regard to the hydrogen beam axis z) displacement of the point where total field is zero. In this work, for the first time, the dependence of single-state selection system performance (or H-maser´s output power) on the currents of the transverse coils, that are placed at the region between magnets, is experimentally obtained. On the dependence, the angles of rotation for spinor that are equal to 0, π/2, π under corresponding quantity of the currents, i. e. transverse coordinates of the zero field, are explicitly determined. The optimal values of the currents, when the maximum of the single-state selection efficiency (the angle of rotation is equal π) is achieved, are defined. Moreover, the operation of the single-state selection system is confirmed by exploration of the H-maser´s power curve and also by double resonance method. The relative amount of the operating atoms in the beam, that defines single-state selection system efficiency, is approximately 70%.
