The ${}_{}{}^{12}{}_{}{}^{}$,13C${(}^{20}$Ne,α) reactions were measured at E=140.2 MeV in order to search for a direct ${}_{}{}^{16}{}_{}{}^{}\mathrm{transfer}$ process. In the reaction with the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ target, prominent broad peaks were observed, while the spectrum with the ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ target shows a smooth continuum with much smaller structures in the high excitation region. Kinematics of the structures in the ${}_{}{}^{12}{}_{}{}^{}\mathrm{Ne}$,α) reaction demonstrates that most of them do not arise from a large cluster transfer, but rather they originate from a sequential ejectile decay.
