The binary decay properties of the 477 nucleus, produced in the 35C1 + 12C reaction, have been investigated at the 35C1 bombarding energies Elab=180 and 200 MeV by means of a kinematical coincidence technique. Binary reaction products show full energy equilibration and a characteristic 1/sin(0om ) angular distribution. The elemental distribution of the fully-damped products is asymmetric, similar to what has previously been observed in the decay of the 56Ni nucleus. Comparison with theoretical model predictions suggests the occurrence of a fusion-fission rather than orbiting process. Moreover the calculations performed using the Extended HauserFeshbach Method reproduce well the experimental fission yields~ A general discussion of orbiting and fusionfission experimental data of light heavy-ion systems is presented in the framework of the calculated number of available open channels for these systems.

The fully energy-damped yields from the 35 Clϩ 12 C reaction have been systematically investigated using particle-particle coincidence techniques at a 35 Cl bombarding energy of ϳ8 MeV/nucleon. The fragmentfragment correlation data show that the majority of events arises from a binary-decay process with rather large numbers of secondary light-charged particles emitted from the two excited exit fragments. No evidence is observed for ternary break-up events. The binary-process results of the present measurement, along with those of earlier, inclusive experimental data obtained at several lower bombarding energies are compared with predictions of two different kinds of statistical model calculations. These calculations are performed using the transition-state formalism and the extended Hauser-Feshbach method and are based on the available phase space at the saddle point and scission point of the compound nucleus, respectively. The methods give comparable predictions and are both in good agreement with the experimental results thus confirming the fusionfission origin of the fully damped yields. The similarity of the predictions for the two models supports the claim that the scission point configuration is very close to that of the saddle point for the light 47 V compound system. The results also give further support for the specific mass-asymmetry-dependent fission barriers needed in the transition-state calculation. ͓S0556-2813͑96͒02407-7͔
