Fusion Between Heavy Neutron-rich Nuclei Using Radioactive and Stable Ion Beams...

Evaporation residues (ER) and fission product were measured following
bombardments of ⁶⁴Ni with radioactive Sn and Te neutron rich isotopes. The experimental setup was tailored to measurements with low intensity
radioactive beams and the data obtained show the obvious enhancement
of ER production (survival) with the addition of neutrons
to the fused system.
A calculation of nucleus-nucleus capture within a WKB formalism
incorporating neutron transfer in a two step approach was performed.
Using global potentials in our calculations we attempted to
predict trends as well as account for measured capture cross
sections in collisions between heavy nuclei with large
neutron excess.
