The lifetimes of states in /sup 152/Gd have been measured by the Doppler-shift recoil-distance technique. Half-lives determined for the 2/sup +/, 4/sup +/, 6/sup +/, 2/sup +/', and 0/sup +/' states are 34.2 +- 1.5, 7.3 +- 0.4, 2.5 +- 0.5, 7.3 +- 0.6, and 37 +- 8 ps, respectively. These states were Coulomb excited with 147-MeV /sup 40/Ar ions and measurements were performed in coincidence with the backscattered projectiles. Comparisons of the experimental values with calculations from the rotational, vibrational, dynamic deformation, boson expansion, and interacting boson models show that the predictions of the latter two theories provide a reasonable overall description of this nucleus, but there are some discrepancies in interband transition strengths. In the course of this work the half-life of the 6/sup +/ state of /sup 156/Gd was also redetermined as 16.7 +- 0.6 ps.
