Investigation of binary processes in reactions 36Ar + 144, 154Sm and 68Zn + 112Sn leading to the formation of neutron-deficient 180, 190Hg composite systems
We investigated asymmetric fission phenomenon of neutron-deficient <sup>180, 190</sup>Hg nuclei, formed in the reactions <sup>36</sup>Ar + <sup>144, 154</sup>Sm and <sup>68</sup>Zn + <sup>112</sup>Sn at energies near and above the Coulomb barrier. Change of comparative contributions of symmetric and asymmetric fission with changing of the excitation energy of the composite system is shown. The problem of entrance channel characteristics influence on the reaction dynamics is studied.
