Study of the complete fusion mechanism in the 16O+63Cu reaction

Absolute values of the cross sections for most evaporation channels consecutive to the complete 16O+63Cu fusion have been measured for incident 16O energies ranging between 40 and 85MeV, through the observation of the corresponding γ activities. They give evidence for a limitation in the contributing incident partial waves for energies above 50MeV. The excitation functions of the various evaporation channels are satisfactorily accounted for, in shape and magnitude, by statistical evaporation calculations performed with the code ALICE. They allow a very precise determination of the variation of the critical angular momentum with the excitation energy of the compound nucleus
