A tungsten oxide target enriched to 30% in ${\mathrm{O}}^{17}$ was bombarded with 12.0-MeV tritons and a similar target enriched to 50% in ${\mathrm{O}}^{18}$ was bombarded with 12.0-MeV deuterons. In both cases, emitted protons were analyzed using a broad-range multiangle spectrograph. The ${\mathrm{O}}^{18}\mathrm{}(d,p)\mathrm{}{\mathrm{O}}^{19}$ reaction was also studied at a bombarding energy of 11 MeV using a gas target and magnetic analysis. Energy levels up to 6.3-MeV excitation in ${\mathrm{O}}^{19}$ were determined and no evidence was found for the recently reported levels at 0.348 and 2.617 MeV. Angular distributions were measured and several new spin and parity assignments were made.
