Abstract

A search for the 2⁺ excitation of the Hoyle state in ¹²C has been performed using the ¹²C(¹²C, 3α)¹²C 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 ¹²C between 9 and 11 MeV; rather upper limits for their excitation in the ¹²C+¹²C inelastic scattering reaction are determined.
