Production of exotic isotopes in complete fusion reactions with radioactive beams

Abstract

The isotopic dependence of the complete fusion (capture) cross section is analyzed in the reactions ${}^{130,132,134,136,138,140,142,144,146,148,150}$Xe+${}^{48}$Ca with stable and radioactive beams. It is shown for the first time that the very neutron-rich nuclei ${}^{186-191}$W can be reached with relatively large cross sections by complete fusion reactions with radioactive ion beams at incident energies near the Coulomb barrier. A comparison between the complete fusion and fragmentation reactions for the production of neutron-rich W and neutron-deficient Rn isotopes is performed.
