Abstract:

The three-dimensional coupled equations that treat simultaneously the relative motion and the internal excitation (temperature) of the heavy ions are studied. They are applied to the 16O+16O collisions at intermediate energies. the fusion window appears for E CM=80 MeV. The temperature of 16O can reach ∼4.5(4.0) MeV for E CM=160(80) MeV, when the heavy ion potential evaluated by using the density-dependent nucleon-nucleon interaction and the chosen friction coefficients estimated with the potential are employed in the equations. The time evolution of the nuclear temperature is obtained consistently with the damping of the relative motion. Important ingredients that control the heavy ion trajectories are discussed.
