The (t, p) reaction on O16, O17 and O18 was studied at a triton bombarding energy of 5.55 MeV, with special attention to the reaction O17(t, p)O19. The position of several energy levels in O19 was established. Good agreement was obtained in some cases between the measured proton angular distributions and the predictions of the plane wave double stripping theory. In other cases the contribution of other reaction modes seems to be appreciable. The spin and parity of the ground and 3.153 MeV levels in O19 obtained by the O17(t, p) reaction were determined unambiguously to be 5 2+ arising from the d3 5 2 and d 5 2s2 1 2 configurations respectively. The 0.093 and 2.775 MeV levels could be identified with the 3 2+ and 9 2+ levels respectively of the d3 5 2 configuration. The results for the O16(t, p)O18 reaction agreed with those of Jaffe et al. who used tritons of 5.50 MeV. In the O18(t, p)O20 reaction the spin and parity assignements for the ground and first three excited levels of O20 were in essential agreement with those of Middleton et al. who bombarded with tritons of 10 MeV.
