Elastic scattering and quasielastic transfer yields have been measured for ${}_{}{}^{76,82}{}_{}{}^{}\mathrm{Se}$${+}^{192,198}$Pt using ${}_{}{}^{76}{}_{}{}^{}\mathrm{Se}$ and ${}_{}{}^{82}{}_{}{}^{}\mathrm{Se}$ beams with laboratory energies of 487.7 and 499.0 MeV, respectively. The variation of the one-neutron transfer yields as function of projectile and target mass can be understood on the basis of Q matching. Quasielastic transfer contributes at most 30% to the total reaction cross section with the remainder probably accounted for by deep-inelastic scattering.
