The charged particles emitted when oxygen is bombarded with 19-Mev deuterons have been studied by a photographic plate method. The angular distributions of the two groups of protons from the reaction ${\mathrm{O}}^{16}(d, p){\mathrm{O}}^{17}$, ${\mathrm{O}}^{17}$ being formed in the ground and 0.88-Mev states, have been found to be in qualitative agreement with the predictions of the stripping theory. Similar measurements have been made for the elastically scattered deuterons and for the $\alpha$ particles from the reaction ${\mathrm{O}}^{16}(d, \alpha ){\mathrm{N}}^{14}$; the curve for the latter shows peaks at about 40°, 90°, and 140°, and is nearly symmetrical about 90°.
