A new two-stage scheme of laser excitation of Zn atoms to the 4snf Rydberg states is presented. A modification of the laser-microwave spectrometer of the Institute of Radio Astronomy intended for recording of Rydberg spectra of Zn atoms is described.Key words: Rydberg atom, zinc, laser excitation, spectrometerManuscript submitted 18.06.2014Radio phys. radio astron. 2014, 19(4): REFERENCES1.
