Further evidence for resonance anomalies in the12C+16O system

Abstract
Excitation functions for six nuclides resulting from the 16O+12C reaction, as well as for inelastic scattering to the 3- state of 16O, have been measured by gamma -ray techniques in the centre-of-mass energy range ECM=12.8-18.2 MeV and a complete fusion excitation function deduced. Resonance anomalies, which may be due to the excitation of quasimolecular states, are observed at 14.7, 16.7 17.6 and 18.6 MeV. These and other results are considered in terms of theoretical models for quasimolecular states.
