Abstract
A new setup is proposed to produce and investigate heavy neutronrich 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 neutronrich nuclides along the neutron closed shell N = 126 is extremely important for nuclear astrophysics investigations and in particular for the understanding of the rprocess of astrophysical nucleosynthesis A new way was recently proposed for the production of these nuclei via lowenergy multinucleon transfer reactions The estimated yields of neutronrich nuclei are found to be rather high in such reactions and several tens of new nuclides can be produced for example in the nearbarrier collision of 136Xe with 208Pb This setup could definitely open a new opportunity in the studies at heavyion facilities and will have significant impact on future experiments
