The quasifission process is a close relative of fusion-fission. In both reaction channels, two nuclei collide to form a system that splits into two fragments. However, while fully equilibrated compound systems are formed during fusion-fission reactions, in quasifission, the system is out of equilibrium during the process. In this paper, we show that the experimental measurement of the atomic number of quasifission fragments reveals a strong even-odd staggering in the isotopic yields, which, in turn, can be used as a marker for nucleon dynamics. The measured data demonstrate the action of two distinct nucleon drift flows, which can be associated with the initial isospin equilibration and the subsequent mass drift.
