The γ-ray emission from the dynamical dipole formed in heavy-ion collisions during process leading to fusion was measured for N/Z asymmetric reaction 16O + 116Sn at beam energies of 8.1 and 15.6 MeV/nucleon. High-energy γ-rays charged particles were coincidence with heavy recoiling residual nuclei. data are compared those symmetric 64Ni 68Zn bombarding 4.7 7.8 MeV/nucleon, same CN excitation as calculated kinematics. yield high-energy 16O-induced is found exceed that thermalized excess increases energy. rather good agreement predictions based on Boltzmann–Nordheim–Vlasov model. In addition, a comparison existing mass region performed extract information moment dependence.
