Popis: A new setup is proposed to produce and investigate heavy neutron-rich nuclei located along the neutron closed shell N = 126. This "blank spot" of the nuclear map can be reached neither in fusion-fission reactions nor in fragmentation processes widely used nowadays for the production of exotic nuclei. The present limits of the upper part of the nuclear map are very close to stability while the unexplored area of heavy neutron-rich nuclides along the neutron closed shell N = 126 is extremely important for nuclear astrophysics investigations and, in particular, for the understanding of the r-process of astrophysical nucleosynthesis. A new way was recently proposed for the production of these nuclei via low-energy multi-nucleon transfer reactions. The estimated yields of neutron-rich nuclei are found to be rather high in such reactions and several tens of new nuclides can be produced, for example, in the near-barrier collision of 136Xe with 208Pb. This setup could definitely open a new opportunity in the studies at heavy-ion facilities and will have significant impact on future experiments. © 2013 Springer Science+Business Media Dordrecht. ispartof: pages:109-113 ispartof: Hyperfine Interactions vol:216 issue:1-3 pages:109-113 ispartof: 6th International Conference on Laser Probing (LAP) location:Paris, FRANCE date:4 Jun - 8 Jun 2012 status: published
