【 摘 要 】

We are the first to experimentally observe a magnetic resonance signal of 62S1/2Cs atoms by absorption of light from a helium lamp that was used to optically orient metastable 23S1He atoms. The amplitude of the cesium signal proved to be almost three orders of magnitude lower than the amplitude of the magnetic resonance of 23S1He atoms. The theoretical explanation of the effect is presented.
