Abstract
Evaporation residue cross sections for $^{124,126,127,128}$Sn+$^{64}$Ni
and $^{132}$Sn+$^{58}$Ni have been measured to study the effects of
neutron excess in neutron-rich radioactive nuclei on fusion. For the reactions
with $^{64}$Ni, the fusion probability does not decrease with
increasing neutron excess in Sn, contrary to the result of the stable beam
Sn+Zr measurement. A comparison of the reduced evaporation residue cross
sections for $^{126}$Sn+$^{64}$Ni and $^{132}$Sn+$^{58}$Ni, which make the same
compound nucleus, shows that the fusion probability is indistinguishable
for reactions involving the same atomic elements but
different isotope combinations.
