摘要: The fully energy-damped yields from the $^{35}\mathrm{Cl}$${+}^{12}$C reaction have been systematically investigated using particle-particle coincidence techniques at a $^{35}\mathrm{Cl}$ bombarding energy of \ensuremath{\sim}8 MeV/nucleon. fragment-fragment correlation data show that majority events arises binary-decay process with rather large numbers secondary light-charged particles emitted two excited exit fragments. No evidence is observed for ternary break-up events. binary-process results present measurement, along those earlier, inclusive experimental obtained several lower energies are compared predictions different kinds statistical model calculations. These calculations performed transition-state formalism and extended Hauser-Feshbach method based on available phase space saddle point scission compound nucleus, respectively. methods give comparable both in good agreement thus confirming fusion-fission origin damped yields. similarity models supports claim configuration very close to light $^{47}\mathrm{V}$ system. also further support specific mass-asymmetry-dependent fission barriers needed calculation. \textcopyright{} 1996 American Physical Society.
