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