An analysis of the ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$${(}^6$Li,dα${)}^{13}$C reaction in the collinear (${\theta }_{\mathrm{d}=0\mathrm{}}$°) and noncollinear (${\theta }_{\mathrm{d}=10\mathrm{}}$°,8°) geometry is made for two peaks observed in the deuteron energy spectrum and corresponding to excitation energies of 16.1 and 13.6 MeV in the ${}_{}{}^{17}{}_{}{}^{}\mathrm{O}$ nucleus. It is shown that the reaction proceeds via a direct alpha-transfer process which populates doublets of interfering ${}_{}{}^{17}{}_{}{}^{}\mathrm{O}$ levels. Spins, weights, and parities of these levels are obtained by means of a least square procedure.
