Title: The role of the Heisenberg principle in constrained molecular dynamics model

Abstract

In this study, we implement the Heisenberg principle into the Constrained Molecular Dynamics model with a similar approach to the Pauli principle using the one-body occupation probability $$\bar{f}_i$$. Results of the modified and the original model with comparisons to data are given. The binding energies and the radii of light nuclei obtained with the modified model are more consistent with the experimental data than the original one. The collision term and the density distribution are tested through a comparison to p+12C elastic scattering data. Some simulations for fragmentation and superheavy nuclei production are also discussed.
