Complex fragments of nuclear charge $Z$ from 4 to 13 were measured at five laboratory angles by use of surface-barrier-detector telescopes. Coincident $\ensuremath{\gamma}$ rays were measured in a $4\ensuremath{\pi}$ geometry using 64 NaI detectors. Kinematical analysis of the fragments revealed that those of $Z$ between 4 and 9 are consistent with the decay of a compound nucleus formed in a complete fusion reaction. $\ensuremath{\gamma}$ rays of excited states of $^{12}\mathrm{C}$, $^{15}\mathrm{N}$, and $^{16}\mathrm{O}$ were measured and effective temperatures of about 2 MeV were extracted. Hauser-Feshbach calculations reproduce the measured cross sections and the effective temperatures very well.
