In-plane angular correlations have been investigated in the ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$${(}^{16}$O${,}^{12}$C α), ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$${(}^{16}$O${,}^{12}$C α), and ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$${(}^{10}$B${,}^6$Li α), reactions at 64, 64, and 48 MeV, respectively. Two sequential processes have been clearly identified, namely, projectile sequential decay and incomplete fusion followed by particle reemission. The analysis is based on three-body kinematics and model fits of experimental angular correlation functions.
