Study of the Static Properties of the Neutron Rich Nuclei in the Framework of the Quantum Molecular Dynamics

One of the most successful models to study the static properties of the neutron rich nuclei is the Quantum Molecular dynamic (Q M D). we applied Q M D model to study the center of mass positions, halo structure, binding energies and root mean square radii for Li, Be and B isotopes. the construction of minimum - energy intrinsic states is made by the use of the frictional cooling method. the model Hamiltonian includes the non-relativistic kinetic, Skyrme type interaction and coulomb interaction parts while the symmetry energy terms with parameters which guarantee the infinite nuclear matter properties. the width of nucleon wave packets was treated as time-dependent dynamical variables. it is shown that the neutron rich nuclei like Li, Be, and B has halo structure and also the binding energies and root mean square radii of these isotopes can be simultaneously produced . Our calculations are proceed at 2-different equations of state (E O S) for the interaction potential parameters. these E O S are soft equation of state (S E O S) and hard equation of state (H E O S)
