The excitation function of the reaction C12([alpha], [gamma])016 has been studied over the region E[subscript alpha] = 2.8 to 8.3 MeV using a NaI(T1) detector and enriched C12 targets. Resonances were observed at E[subscript alpha] = 3.24, 3.58, 4.26, 5.81, 7.05, 7.88 and 8.13 MeV, corresponding to 016 states at E[subscript x]= 9.59, 9.85, 10.36, 11.52, 12.45, 13.07 and 13.26 MeV. Radiative widths [Gamma subscript gamma] for ground state radiation from the states at 9.59, 9.85, 11.52 and 12.45 MeV were measured to be 0.022 [plus or minus] 0.005, 0.0059 [plus or minus] 0.0006, 0.66 [plus or minus] 0.09 and 7 [plus or minus] 1 eV, respectively. Radiative widths for cascade radiation from the 9.85 and 10.36 MeV states through intermediate states of 016 were measured to be 0.0012 [plus or minus] 0.0004 and 0.046 [plus or minus] 0.006 eV, respectively. Interference effects in ground state radiation from the 13.07 MeV([...]) state support evidence for an underlying 2+ state at nearly the same energy. Other information on excited states of 016 is presented.
