From a measurement of the cross section for 12C(alpha, gamma)16O at the Ealpha = 4.253+/-0.014 MeV(E = 10.352+/-0.011 MeV) resonance, the radiative width for the 10.35 MeV (Jpi = 4+) to 6.92 MeV (Jpi = 2+) transition was determined to be Gammagamma = 58+/-7 meV. This is somewhat higher than the value predicted by large j-j shell-model calculations, but agrees well with predictions based on the
