Correlation among intermediate structures in binary and fusion-evaporation channels of theO18+C12reaction

Abstract
The O18 + C12 reaction has been studied from 20.0 to 32.4 MeV (c.m.) in steps of 200 keV. Twenty-one γ-ray excitation functions have been investigated, seven of them as binary, and fourteen as fusion-evaporation exit channels. Most of the excitation functions display structures which are strongly correlated. In particular, a one-to-one correspondence between the peaks of summed binary and summed fusion-evaporation excitation functions has been established. A comparison with the C14 + O16 system leading to the same Si30 composite nucleus is presented.
