Quasifission and fusion-fission processes in the reactions Kr-78+Ca-40 and Kr-86+Ca-48 at 10 MeV/nucleon bombarding energy

摘要

Within the dinuclear system model the charge, mass, and isotopic distributions of the products in the reactions Kr-78 + Ca-40 and Kr-86 + Ca-48 are predicted at bombarding energy 10 MeV/nucleon. The heavy-ion phase-space exploration code is applied to take into consideration the pre-equilibrium emission of light particles. The competition is treated between complete fusion followed by the decay of compound nucleus and quasifission channels. The possible explanation of the odd-even staggering in the yield of the final reaction products at high excitation energies is discussed.
