Isospin dynamics and production of exotic nuclei up to 70 AMeV

The available experimental projectile-like fragment data from nucleus-nucleus collisions at beam energies from the Coulomb barrier up to 70 AMeV and various projectile-target asymmetries are investigated. The scenario involving pre-equilibrium emission followed by deep-inelastic transfer or incomplete fusion leads to consistent agreement in most of the cases. At beam energies around and above 50 AMeV there are signals of the mechanism of neutron loss (dynamical emission) preceding the thermal equilibration. At beam energies below 10 AMeV, deep-inelastic transfer appears to be affected by the possible extended nuclear profile in the window (neck) region.
