摘要: The lifetimes or limits on the of five levels in O/sup 18/ and six F/sup were measured by Doppler shift attenuation method. Large initial GAMMA oppler shifts for gamma rays from obtained bombarding tritium with 11 to 16-Mev oxygen ions a tandem accelerator. mean psec 1.98m 3,55m 3,63m 3,92m abd 4,45- Mev found be 3.7 plus minus 0.7,>3, 3 1, 0.18 0.06 <0.3,)1.0, 2.0 1.0, 0.70 0.20, 1.1 0.2, respectively. significance these measurements is discussed.
