  The dynamical mechanism of multinucleon transfer (MNT) reactions has been
investigated within the dinuclear system (DNS) model, in which the sequential
nucleon transfer is described by solving a set of microscopically derived
master equations. Production cross sections, total kinetic energy spectra,
angular distribution of formed fragments in the reactions of $^{124,132}$Sn+
$^{238}$U/$^{248}$Cm near Coulomb barrier energies are thoroughly analyzed. It
is found that the total kinetic energies of primary fragments are dissipated
from the relative motion energy and rotational energy of the two colliding
nuclei. The fragments are formed in the forward angle domain. The energy
dependence of the angular spectra is different between projectile-like and
target-like fragments. Isospin equilibrium is governed under the potential
energy surface. The production cross sections of neutron-rich isotopes are
enhanced around the shell closure.
