Abstract

For production and investigation of heavy neutron rich nuclei devoted the new setup, which is under construction at Flerov Laboratory for Nuclear Reactions (FLNR) - JINR, Dubna now. This setup is planned to exploit available beams from the U-400M cyclotron in low energy multi-nucleon transfer reactions to study exotic neutron-rich nuclei located in the “north-east” region of nuclear map. Products from 4.5 to 9 MeV/nucleon heavy-ion collisions, such as 136Xe on 208Pb, are to be captured in a gas cell and selectively laser-ionized in a sextupole (quadrupole) ion guide extraction system.

Highlights

In order to produce and study multinucleon transfer reaction products the GAs cell based Laser ionization an Separation setup (GALS) is designed at Flerov Laboratory for Nuclear Reactions (JINR)
For production and investigation of heavy neutron rich nuclei devoted the new setup, which is under construction at Flerov Laboratory for Nuclear Reactions (FLNR) - JINR, Dubna
The ions’ mean time of flight, mean longitudinal kinetic energy KEx, their energy dispersion σKEx and sextupole ion guide (SPIG) efficiency depending on the distance from the gas cell to the skimmer between the first and second cameras of the vacuum chamber are shown in Table 1, statistics of 200 ions used for each case, the ions’ parameters were captured at the end of SPIG
