Zeroing of magnetic resonance signals when optically lamps pumping of alkali metal atoms in cells with wall coating


The paper presents the experimental investigation results of ‘zeroing’ effect of magnetic resonance signals on the upper hyperfine F = I + J  level of the ground    2 S1/ 2 state of alkali metal atoms within cells with anti-relaxation wall coating in optical lamp pumping with D2- or (D1 + D2)-emission lines depending on cell temperature. It has been found that, when there are no mutual atomic collisions in the excited 2Р3/2 state, the reason for occurrence of zeroing signals is a feature of magnetic resonance indication by optical cyclic transition of D2-line in the aggregate with a spin exchange in F = I + J state when changing the temperature of the cell. The engineering application of the results of research is given.
