Pickup ($p, d$) reactions on ${\mathrm{B}}^{11}$, ${\mathrm{C}}^{14}$, ${\mathrm{O}}^{16}$, and ${\mathrm{O}}^{18}$ have been observed at proton energies ranging from 17.6 to 20 MeV. Also, ($p, t$) reactions on ${\mathrm{C}}^{14}$ and ${\mathrm{O}}^{18}$ were observed. Angular distributions were taken and absolute differential cross sections were obtained for all reactions except ${\mathrm{C}}^{14}(p, d){\mathrm{C}}^{13}$ and ${\mathrm{C}}^{14}(p, t){\mathrm{C}}^{12}$. The deuteron results were analyzed using the plane-wave Butler formalism and reduced widths and spectroscopic factors were calculated. The results indicate that the single-particle reduced width is a function of the binding energy of the transferred nucleon, which may indicate that the plane-wave approximation is not completely adequate for analyzing stripping and pickup experiments on light nuclei. The ($p, t$) results, when compared to those for the inverse ($t, p$) reactions, indicate that such experiments may possibly be described using a simple stripping formalism.
