Absolute cross sections for isotopically identified products formed in multinucleon transfer the (136)Xe+(198)Pt system at ∼8 MeV/nucleon are reported. The isotopic distributions obtained using a large acceptance spectrometer demonstrated production of "hard-to-reach" neutron-rich isotopes Z<78 around N=126 shell closure far from stability. main contribution to formation these exotic nuclei is shown arise collisions with small kinetic energy dissipation. present experimental finding...
