摘要
We report a spectroscopy experiment of the ^199Hg＋ ions are optically pumped by a discharge lamp and splitting is measured to be 40507347996.8（0.1）Hz by line width as 30mHz is also observed. This progress ion frequency standards. ground state hyperfine splitting in a linear ion trap. The cooled by helium buffer gas. The ground state hyperfine the mierowave-optical double-resonance method. A nsrrow builds the foundation for the realization of trapped ^199Hg＋
