The hyperfine structure of 276.9-nm atomic transition has been studied by the resonant ionization spectroscopy method at mass-separator IRIS (Investigation Radioactive Isotopes on Synchrocyclotron), Petersburg Nuclear Physics Institute (PNPI) for odd Tl isomers with $I$ = 9/2 and $A$ 187--197. A differential anomaly $6p{}^{\phantom{\rule{0.16em}{0ex}}2\phantom{\rule{-0.16em}{0ex}}}{P}_{1/2}$ $7s{}^{\phantom{\rule{0.16em}{0ex}}2\phantom{\rule{-0.16em}{0ex}}}{S}_{1/2}$atomic states in...
In-source laser spectroscopy experiments for neutron-deficient thallium isotopes at the 276.9-nm atomic transition have been carried out Investigation of Radioactive Isotopes on Synchrocyclotron facility Petersburg Nuclear Physics Institute. New data isotope shifts and hyperfine structure ${}^{183\ensuremath{-}207}$Tl isomers are presented. The changes in mean-square charge radii magnetic-moment values deduced. It is shown that nuclear properties Tl smoothly change neutron midshell beyond...
Isotope shift relative to $^{209}\mathrm{Bi}$ and hyperfine splitting for $^{211,213}\mathrm{Bi}$ have been measured by in-source laser spectroscopy at the 306.77-nm atomic transition. The pronounced shell effect both in radii magnetic moments Bi isotopes $N=126$ has observed. isotopic trend of moment $9/{2}^{\ensuremath{-}}$ ground states even-$N$ qualitatively explained change first-order core-polarization correction. possible influence octupole degree freedom on behavior $N>126$ discussed.
In-source laser spectroscopy experiments on bismuth isotopes using the 306.77-nm atomic transition have been carried out at Investigation of Radioactive Isotopes Synchrocyclotron facility Petersburg Nuclear Physics Institute. New data for isotope shifts and hyperfine structures $^{193,195,197}\mathrm{Bi}^{\mathrm{g},\mathrm{m}}$ isomers obtained. A large isomer shift between $I=1/{2}^{+}$ (intruder) $I=9/{2}^{\ensuremath{-}}$ (normal) states has found. The charge radii...
New laser installation for the resonance ionization spectroscopy in a ion source and rare isotope production has been recently put into operation at IRIS (Investigation of Radioactive Isotopes on Synchrocyclotron) facility (Petersburg Nuclear Physics Institute, Gatchina). This is significant improvement previous target-laser device mass-separator, working on-line with 1 GeV proton beam PNPI Institute) synchrocyclotron. It makes possible us to get isobarically clean radioactive beams great...

The HADES collaboration uses the e + − production as a probe of resonance matter produced in collisions at incident energies 1-3.5 GeV/nucleon GSI. Elementary reactions provide useful references for these studies and give information on Dalitz decays (R→Ne ). Such processes are sensitive to structure time-like electromagnetic baryon transitions kinematic range where (off-shell) vector mesons play crucial role. Results obtained proton-proton commissioning pion-beam experiment reported...
The branching of the ${2}^{+}\ensuremath{\rightarrow}{0}^{+}$ transition in $^{92}\mathrm{Sr}$ has been measured to 0.032(4) per $^{92}\mathrm{Rb}$ decay. It confirms an earlier measurement which was discarded nuclear data evaluations because a contradiction with accepted lower log $\mathit{ft}$ limits. conflict could be solved assuming that close half decay intensity, mostly as high-energy ground-state transitions, is missing scheme.
In-target resonance ionization was applied for the first time, to our knowledge, isotope-shift and hyperfine splitting measurements at Investigation of Radioactive Isotopes on Synchrocyclotron (IRIS) facility. The production yield short-lived Gd atoms selectivity laser appear be nearly two seven times higher, respectively, compared with those a conventional target--laser-ion-source system. Changes in mean-square charge radii...
Presently, the cyclotrons are playing a very important role in production of radionuclides for medicine, which safe and reliable installations.From radioisotopes produced with cyclotrons, it is rather easy to select one that has appropriate nuclear-physical characteristics medical use, comparison ones reactors.At PNPI, high current cyclotron C-80 energy extracted proton beam 40-80 MeV up 200 µA under construction.One main goals wide spectrum diagnostics therapy.At present time, project...
