“…This method has been proposed in 1992 [4] and subsequently intensively studied (first at LISOL) and developed [5][6][7][8][9][10][11][12][13]. Known as In-Gas Laser Ionization and Spectroscopy (IGLIS), it is based on stopping of nuclear reaction products in a gas cell and subsequent selective resonance laser ionization [5][6][7][8][9][10][11][12][13].…”

Abstract.A project devoted to the production and study of neutron rich heavy nuclei (GALS -project) is being realized at Flerov Laboratory for Nuclear Reactions (FLNR) -JINR. GALS is planned to exploit available beams from the U-400M cyclotron in low energy multi-nucleon transfer reactions to study exotic neutronrich nuclei located in the "north-east" region of nuclear map. Products from 4.5 to 9 MeV/nucleon heavy-ion collisions, such as 136 Xe on 208 Pb, are to be captured in a gas cell and selectively laser-ionized in a sextupole (quadrupole) ion guide extraction system.

a b s t r a c tThe in-gas laser ionization and spectroscopy (IGLIS) technique is used to produce and to investigate short-lived radioactive isotopes at on-line ion beam facilities. In this technique, the nuclear reaction products recoiling out of a thin target are thermalized and neutralized in a high-pressure noble gas, resonantly ionized by the laser beams in a two-step process, and then extracted from the ion source to be finally accelerated and mass separated. Resonant ionization of radioactive species in the supersonic gas jet ensures very high spectral resolution because of essential reduction of broadening mechanisms. To obtain the maximum efficiency and the best spectral resolution, properties of the supersonic jet and the laser beams must be optimized. To perform these studies a new off-line IGLIS laboratory, including a new high-repetition-rate laser system and a dedicated off-line mass separator, has been commissioned. In this article, the specifications of the different components necessary to achieve optimum conditions in laser-spectroscopy studies of radioactive beams using IGLIS are discussed and the results of simulations are presented.

“…The combination of low production cross sections, the lack of stable isotopes, and correspondingly only a limited number of reliably determined optical transitions available from literature add to the challenge of performing laser spectroscopy on these heaviest elements. Due to the scarcity of ground-state nuclear structure information in this region of the nuclear chart, efforts are under way to develop suitable techniques which provide the required sensitivity to efficiently make use of the limited quantity of isotopes which can be produced [4][5][6].…”

High-resolution laser spectroscopy of long-lived plutonium isotopes Voss, Annika; Sonnenschein, Volker; Campbell, P.; Cheal, B.; Kron, T.; Moore, Iain; Pohjalainen, Ilkka; Raeder, S.; Trautmann, N.; Wendt, K.Voss, A., Sonnenschein, V., Campbell, P., Cheal, B., Kron, T., Moore, I., . . . Wendt, K. (2017 Long-lived isotopes of plutonium were studied using two complementary techniques, high-resolution resonance ionization spectroscopy (HR-RIS) and collinear laser spectroscopy (CLS). Isotope shifts have been measured on the 5f 6 7s 2 7 F 0 → 5f 5 6d 2 7s (J = 1) and 5f 6 7s 2 7 F 1 → 5f 6 7s7p (J = 2) atomic transitions using the HR-RIS method and the hyperfine factors have been extracted for the odd mass nuclei 239,241 Pu. CLS was performed on the 5f 6 7s 8 F 1/2 → J = 1/2 (27 523.61 cm −1 ) ionic transition with the hyperfine A factors measured for 239 Pu. Changes in mean-squared charge radii have been extracted and show a good agreement with previous nonoptical methods, with an uncertainty improvement by approximately one order of magnitude. Plutonium represents the heaviest element studied to date using collinear laser spectroscopy.
