On the Stability of Nuclei Propagating with Momentum Dependent Interactions
Abstract
The present study deals with the role of momentum dependent interactions (MDI) in heavy-ion collisions using a semi-classical nuclear model. Our goal here is to understand the stability of nuclei propagating under the influence of momentum dependent interactions. For this study, a semi-classical theory in terms of quantum molecular dynamics model (QMD) is employed. The role of momentum dependent interactions is studied by employing static as well as momentum dependent interactions and then studying the time evolution of the phase space of various fragments. Our observations, spanning over entire periodic table, suggest that momentum dependent interactions destabilize the stable nuclei which start emitting nucleons artificially if propagating with momentum dependent interactions. One should, therefore, be careful while studying the multifragmentation with momentum dependent interactions.
