Abstract
Evaporation residue cross sections have been measured following the fusion of with , forming the compound nucleus . These are compared with existing data for the same compound nucleus formed following fusion reactions with , , , and projectiles. At energies where the reduced cross sections of evaporation residues would be expected to be the same for all reactions, those for the heavier projectiles are typically a factor of 10 smaller than those for . This inhibition is attributed to strong competition of quasifission with fusion at the low angular momenta associated with evaporation residue formation.
