Study of Binary Processes in the Reactions of 36Ar + 144, 154Sm and 68Zn + 112Sn Leading to the Formation of Neutron-Deficient Compound 180, 190Hg Nuclei

A study is performed of the asymmetric fission of neutron-deficient mercury 180, 190Hg isotopes obtained in the reactions of 36Ar + 144, 154Sm and 68Zn + 112Sn at incident energies near and above the Coulomb barrier. The relative contributions from asymmetric and symmetric fission change along with the excitation energy of the fissile compound nucleus. The effect the characteristics of the entrance channel have on the dynamics of the reaction is studied.
