A measurement of the cascade y radiation from the 7.65-MeV J» = 0+ state in "C is reported. The cascade y radiation through the 4.44-MeV J = 2+ state in "C is responsible for 98% of stellar ' C production, the reining 2% proceeding by EO pair decay. The two E2 y rays were measured in coincidence with inelastically scattered protons which resonantly populated the 7.65-MeV state at E, = 10.48 MeV. A high efficiency detection system was used, consisting of four 12.5' X 12.5~NaI y detectors and four silicon surface barrier particle counters. A value of (4.09 + 0.29) X 10 was obtained for the radiative branching ratio, in agreement with the larger of the two sets of values previously reported.
