On the stability of nuclei in semi-classical quantum molecular dynamics model

The stability of nuclei is discussed with respect to the width of the Gaussian wave packets within Quantum Molecular Dynamics model. A detailed study is carried out by taking different equations of state (i.e., static soft and hard and the momentum dependent soft and hard) for the selected nuclei from 12C to 197Au. A comparison is done by using standard and broader Gaussian wave packets. We find that the nuclei propagating with broader Gaussian wave packets remain stable for entire reaction time span.
