Absolute differential cross sections are presented for the reactions ${\mathrm{C}}^{12}({\mathrm{Li}}^6, p){\mathrm{O}}^{17}$ (ground state and first three excited states) and ${\mathrm{C}}^{12}({\mathrm{Li}}^6, d){\mathrm{O}}^{16}$ (ground state), for laboratory energies from 3.4 to 4.0 MeV. Total cross sections are about 1 mb at 4.0 MeV. Fluctuations in the angular distributions and total cross sections suggest that the reactions proceed via the compound nucleus ${\mathrm{F}}^{18}$ which is excited to the region of over-lapping levels. This is in contrast to the predominantly direct character of the previously studied reaction ${\mathrm{C}}^{12}({\mathrm{Li}}^6, \alpha ){\mathrm{N}}^{14}$.
