Proton capture reactions on targets of ${}_{}{}^{11}{}_{}{}^{}\mathrm{B}$, ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, and ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$ were measured from $E_{\mathrm{p}=20\mathrm{}}$ to 100 MeV. The energy dependence of the ${\theta }_{\gamma }$=60° differential cross sections are presented for captures populating the ground states of ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$, ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{17}{}_{}{}^{}\mathrm{F}$, and ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$. Differential-cross-section and analyzing-power angular distributions are presented at bombarding energies of $E_{\mathrm{p}=20.8\mathrm{}}$, 28.35, 49.2, and 49.69 MeV. Calculations from two capture-reaction models are compared to the data.
