The Stochastic Mean Field model including momentum dependent interaction is developed. We also incorporate the standard Skyrme effective interaction into the model, employing several parameterizations available in the literature. Within the framework of this model, we study the effects of momentum dependent interaction on low-energy reaction mechanisms, which are affected by the properties of nuclear matter at sub-saturation regions. In particular, the effect on collective excitation mechanisms, such as dipole mode excitations, will be investigated. The role of the isovector terms of the nuclear interaction, connected
to the symmetry energy of the nuclear EoS, will be discussed. On the other hand, we also investigate the impact of the nuclear symmetry energy on some features of compact stars. We use different EoS to study neutron stars by solving the TOV equations. We demonstrate that different EoS give different mass and radius relation for neutron stars even when they have exactly the same ground state (gs) properties.
