Simulation of fusion and quasifission in nuclear reactions leading to production of superheavy elements using the Constrained Molecular Dynamics model
Abstract
Fusion dynamics and the onset of quasifission in reactions, leading to production of superheavy nuclei are investigated using the constrained molecular dynamics model. Constraints on the parameters of the nuclear equation of state are derived from experimental fusion probabilities. Here, the obtained constraint on the modulus of incompressibility of nuclear matter K_{0} = 240 –260 MeV is consistent with the results of previous study using the BoltzmannUehlingUhlenbeck equation and also with constraints derived using the recent neutron star binary collision event GW170817. Unlike the modulus of incompressibility of symmetric nuclear matter, the stiffness of the densitydependence of symmetry energy influences the fusion probability only weakly.
