The inclusive energy spectra of the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$(${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$,${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$)${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ alpha transfer reaction and of the ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$(${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$,${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$)${}_{}{}^{32}{}_{}{}^{}\mathrm{S}$ alpha transfer reactions have been studied at four different ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ incident energies: 50, 60, 68, and 72 MeV. The shape of the various energy spectra and the corresponding angular distributions are reproduced by a diffractional model calculation based on mutual excitation of the two residual partners.
