Measurements of multineutron transfer reactions in {sup 58}Ni+{sup 124}Sn collisions are analyzed in a simplified coupled-channels model. Successive one-neutron and direct two-neutron transfer couplings are included explicitly, together with 2{sup +} and 3{sup {minus}} excitations of projectile and target. Capture reactions, i.e., fusion and deep-inelastic reactions, are described by ingoing-wave boundary conditions. Quasielastic charged-particle transfer reactions are not treated explicitly but are simulated by a weak imaginary potential. The model provides a comprehensive description of the measured reaction and elastic scattering data, from far below to well above the Coulomb barrier. We find that subbarrier capture rates are enhanced by couplings to neutron transfer channels but the enhancement is not as large as caused by couplings to low-lying surface modes. {copyright} {ital 1998} {ital The American Physical Society}
