Multinucleon Transfer in 40 Ar + 64 Ni collisions at 15 MeV/nucleon explored via Studies of Momentum Distributions

We present a detailed analysis of the mass and the momentum per nucleon distributions of ejectiles from the reaction of a 40 Ar beam at 15 MeV/nucleon with a 64 Ni target. The experimental data were obtained in a previous work with the MARS separator at the Cyclotron Institute of Texas A&M University. The experimental distributions are compared with two dynamical models, the Deep-Inelastic Transfer (DIT) model and the Constrained Molecular Dynamics (CoMD) model, followed by the de-excitation code GEMINI. Both models describe the experimental data to some extent and further optimization is underway in efforts to deepen our understanding of the mechanisms taking place in the production of exotic neutron-rich nuclides in the Fermi energy regime.
