Karazin popup.description2 Object of investigation - Zinc atoms in the preionization states. Purpose of investigation - high-precision spectroscopy of singlet and triplet Zn-atoms in the high-excited (Rydberg) states. Methods of investigation - method of field ionization with multi-stages laser-microwave excitation of neutral Zinc atoms. Results: 1.Atom-beam microwave spectrometer intended for investigation of absorption spectra of singlet Zn-atoms in the D, F, G Rydberg states within frequency range of 34 - 250 GHz was improved. One-photon and two-photon resonances of n1D2?(n+1)1D2, n1D2?(n-1)1F3, n1F3?(n+1)1D2, n1F3?n1D2, n1F3?(n+1)1F3, n1F3?(n+1)1G4types were detected. 2.Frequencies of 24 resonances of the kind were measured for n = 28 ? 40. Parameters for calculation of quantum defect of Zn I atom were obtained for D, F, and G singlet states. 3.Atom-beam microwave spectrometer intended for investigation of absorption spectra of triplet Zn-atoms in the S, P, D, F, G Rydberg states within frequency range of 34 - 250 GHz was improved. One-photon and two-photon resonances of n1F2?(n-1)1D3, n1F3?(n+1)1F3, n1F3?(n+1)1G4 types were detected. 4.Frequencies of 87 resonances of the kind were measured for n = 28 ? 40. Parameters for calculation of quantum defect of Zn I atom were obtained for S, P, D, F, G triplet states. 5.It is assigned to ionization potential of atoms of zinc/ 6.Parameters of polarizability of Zn+ ion were obtained.
