Abstract
A high-energy-resolution magnetic spectrometer has been used to measure the excitation energy spectrum to search for the excitation of the 7.65 MeV, Hoyle state. By measuring in the diffractive minimum of the angular distribution for the broad background, evidence is found for a possible state at 9.6(1) MeV with a width of 600(100) keV. The implications for the reaction rate in stellar environments are discussed.
