The Improved Quantum Molecular Dynamics (ImQMD) Model
As a semiclassical microscopic dynamics model, the quantum
molecular dynamics (QMD) model was proposed
for simulating heavy-ion collisions (HICs) at intermediate and
high energies. To extend the QMD model for the study of heavy-ion reactions at energies
around the Coulomb barrier, the ImQMD model was proposed
based the QMD framework with some modifications:
- The standard Skyrme force is adopted for describing not only
the bulk properties but also the surface properties of nuclei.
- The Fermi constraint (via two-body elastic & inelastic scattering) is used to consider the fermionic properties of nucleons.
- The mass dependence of the wave-packet width is considered for a better description
of the surface properties of finite nuclei and the fluctuations
in reactions.
- The momentum dependence of the nucleon-nucleon interaction according to the Skyrme force is involved in the verion (ImQMD05)
for the HICs at intermediate energies.
The ImQMD model is mainly applied on the study of heavy-ion collisions at intermediate and low
energies.
