The lifetimes of nine levels in18F have been measured by using the DSAM and the3He(16O, p)18F inverse reaction at 21 MeV incident energy on Al backings. Particle-gamma coincidence was employed. Levels (MeV) and corresponding lifetime (ps) deduced by a line shape analysis are as follows: 1.70 (0.897±0.057), 2.10 (4.93±0.78), 2.52 (0.554±0.045), 3.06 (<0.004), 3.13 (0.343±0.022), 3.36 (0.451±0.034), 3.72 (<0.007), 3.79 (1.90±0.20) and 3.84 (0.021±0.004).
