The gamma-ray emission due to dynamical dipole oscillations during fusion process was measured for the N/Z asymmetric reaction (16)O + (116)Sn at 8.1 and 15.6 MeV/u. High-energy gamma-rays and light charged particles were measured in coincidence with the recoiling residual nuclei. The measured yield of the high-energy gamma-rays exceeds that of the thermalized compound nucleus and this extra-yield increases with beam energy. Data are compared with theoretical predictions of a dynamical calculation based on Boltzmann-Nordheim-Vlasov (BNV) model.
