Role of the entrance channel in the production of complex fragments in fusion-fission and quasifission reactions in the framework of the dinuclear system model

Abstract : The influence of entrance channel isospin, charge asymmetry, and bombarding energy on the competition between the complete fusion followed by the decay of compound nucleus and quasifission channels is treated within the dinuclear system model. The charge (mass) distributions of the products in the reactions 16,22O+27Al, 92,78Kr+40Ca, 86Kr+48Ca, 122Sn+12C, 32S+100Mo, 48Ca+144,154Sm, and 20,28Ne+181Ta are calculated at bombarding energies above the Coulomb barrier. The evolution of charge distribution of the complex fragments from the excited rotating nucleus 134Xe with increasing angular momentum and excitation energy is demonstrated.
