Weakly populated multinucleon transfer reactions have been studied in ${}^{64}\mathrm{Ni}{+}^{238}\mathrm{U}$ at ${E}_{\mathrm{lab}}=390 \mathrm{MeV}$ with a time-of-flight magnetic spectrometer. Angular and Q-value distributions for multinucleon transfer channels have been measured up to the pickup of six neutrons and the stripping of six protons. Differential and total cross sections have been extracted and compared with calculations based on the GRAZING model for grazing reactions. The evolution of the system from a quasielastic to a more complex regime and the present limitations to a detailed understanding of these processes are discussed. The results confirm that a clear experimental distinction can be made between the collisions in the grazing (quasielastic and deep-inelastic) regime and in a more complex one (quasifission).
