The 15O(alpha,gamma)19Ne reaction plays a role in the ignition of Type Ix-ray bursts on accreting neutron stars. The lifetimes of states in 19Ne abovethe 15O + alpha threshold of 3.53 MeV are important inputs to calculations ofthe astrophysical reaction rate. These levels in 19Ne were populated in the3He(20Ne,alpha)19Ne reaction at a 20Ne beam energy of 34 MeV. The lifetimes ofsix states above the threshold were measured with the Doppler shift attenuationmethod (DSAM). The present measurements agree with previous determinations ofthe lifetimes of these states and in some cases are considerably more precise.
