The ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}({}_{}{}^6{}_{}{}^{}\mathrm{Li}, {\alpha }_0){}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ reaction has been studied in the incident-energy range of 7-17 MeV at laboratory angles of 5 and 172.5°. These data are compared with previously reported ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({}_{}{}^7{}_{}{}^{}\mathrm{Li}, {\alpha }_0){}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ data over the same energy range in the compound system ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$. Resonant structure is observed in both reactions at $\theta =5^{\circ }$ with correlated structure at 24.7, 27.3, and 28 MeV excitation in ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$. Interpretation of this structure in terms of the resonant-cluster transfer model of Carlson and Johnson is discussed.
