It is demonstrated that the partition of excitation energy between receptor and donor, in quasielastic heavy-ion transfer reactions, at near barrier energies can be studied by [gamma]-ray spectroscopy. Reactions between [sup 161]Dy and [sup 58,61]Ni at bombarding energies 265 and 270 MeV respectively have been studied using the particle-[gamma] coincidence technique. From the observed deexcitation [gamma] rays originating in Ni, we derived the average excitation energy carried by the receptor to be [similar to]0.8 MeV ([ital Q][sub [ital g][ital g]]=2.5 MeV) for [sup 59]Ni and [similar to]2.5 MeV ([ital Q][sub [ital g][ital g]]=4.1 MeV) for [sup 62]Ni in the one-neutron transfer reaction channel. A broad bump peaking about 1 MeV attributed to intrinsic excitation was observed in [sup 160]Dy for the [sup 58]Ni beam and about 1--2 MeV for the [sup 61]Ni beam. Distorted-wave Born approximation analysis reproduces the general features of the excitation-energy partition between the receptor and donor although discrepancies exist when comparing populations of individual final states.
