Abstract

The total fusion cross section for the ${}^{16}O$ + ${}^{12}C$ system has been measured in the ranges $13 MeV <~ E_{c . m .} <~ 27 MeV$ . The cross section is found to increase with bombarding energy up to $E_{c . m .} \approx 17$ MeV but to stay roughly constant at higher energies, in qualitative agreement with predictions of current models. Superimposed on this average cross-section behavior we observe unexpected oscillations with a period of about 3-4 MeV (c.m. energy).
