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

Abstract:
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.
