Using the neutron time-of-flight facility at the Indiana University Cyclotron Facility we have studied (p,n) reactions on the light nuclei ${}_{}{}^{6,7}{}_{}{}^{}\mathrm{Li}$, ${}_{}{}^{10,11}{}_{}{}^{}\mathrm{B}$, and ${}_{}{}^{12,13}{}_{}{}^{}\mathrm{C}$. Double differential cross sections have been measured between ${\mathrm{\theta }}_{\mathrm{lab}}$=0° and 50° in 5° intervals, at ${\mathit{E}}_{\mathit{p}}$=186 MeV. Contributions of the quasifree reaction in the giant resonance region are estimated. Energy spectra of ΔL=1 transitions have been extracted using multipole decomposition analysis. The resulting ΔL=1 spectra are compared with results of photonuclear reactions. Empirical results are also compared with distorted wave impulse approximation calculations.
