Abstract
Quasifission is the primary reaction mechanism that prevents the formation of superheavy elements in heavy-ion fusion experiments. Employing the time-dependent density functional theory approach, we study quasifission in the systems Ca40,48+U238. Results show that for Ca48 projectiles the quasifission is substantially reduced in comparison to the Ca40 case. This partly explains the success of superheavy element formation with Ca48 beams. For the first time, we also calculate the repartition of excitation energies of the two fragments in a dynamic microscopic theory. The differences between both systems are interpreted in terms of initial neutron to proton asymmetry of the colliding partners.
