New laser setup at the IRIS facility. Magnetic moments and mean squared charge radii of neutron deficient Tl isotopes

A new laser installation for the resonance ionization spectroscopy in a laser ion source and for rare isotope production has been put into operation at the IRIS mass-separator, working on-line with the 1 GeV proton beam of the Petersburg Nuclear Physics Institute synchrocyclotron. Isotope shift and hyperfine splitting of 276.9 nm atomic transition in the long chain of Tl isotopes and isomers have been measured. New data on the magnetic moments and changes in mean squared charge radius for ^{183,184,185,185m,186m2,195m,197m}Tl have been obtained.
