A search for the 2(+) excitation of the Hoyle state in C-12 has been performed using the C-12(C-12, 3a)C-12 reaction at a beam energy of 101.5 MeV. An angular correlation analysis was used to suppress known contributions to the excitation energy spectrum, enhancing the experimental sensitivity. No strong evidence was found for new states in C-12 between 9 and 11 MeV; rather upper limits for their excitation in the C-12+C-12 inelastic scattering reaction are determined.
