Creating new elements becomes increasingly difficult because the colliding nuclei must be sufficiently neutron-rich and heavy, and live long enough to be suitable as a target or beam. The authors develop a new hybrid model that combines two proven reaction techniques, time-dependent-Hartree-Fock and diffusion over a fusion barrier using the Langevin approach. By comparing different pairs of collision partners to form superheavy nuclei with , an initial, simplified version of the model already sheds some light on the way to synthesize the heaviest elements.
