The mean lives of the 6.91- and 7.12-Mev excited statcs of O/sup 16/ have been measured through a nuclear resonance scattering experiment. The Fig(p, alpha )O/sup 16*/ reaction was used as the source of Doppler-broadened gamma radiation. The relative intensities of the 6.91- and 7.12-Mev gamnaa-ray lines in this source were deternained by observations of the associated alpha particles. From the magnitude of the rresonance fluorescence effect and the angular distribution mean lives of (1.2 plus or minus 0.3) x 10/sup -14/ second for the 6.91-Mev level and (1.0 plus or minus 0.3) x 10/sup -14/ second for the 7.12- Mev level were calculated.
