Abstract

The fusion excitation functions of No249263 are studied by using various reaction systems based on the dinuclear system model. The neutron-rich radioactive beam O22 is used to produce neutron-rich nobelium isotopes, and the new neutron-rich isotopes No261263 are synthesized by Pu242(O22,3n)No261, Pu244(O22,4n)No262, and Pu244(O22,3n)No263 reactions, respectively. The corresponding maximum evaporation residue cross sections are 0.628, 4.649, and 1.638 μb, respectively. The effects of the three processes (capture, fusion, and survival) in the complete fusion reaction are also analyzed. From investigation, a neutron-rich radioactive beam as the projectile and neutron-rich actinide as the target could be a new selection of the projectile-target combination to produce a neutron-rich heavy nuclide.
