Effect of width of the Gaussian wave packet on the energy of vanishing flow in heavy-ion collisions

A good progress has been made on the evolution of various simulation models, which are being used to study various observables, but the stability of ground state nuclei is still a serious issue for many dynamical models. This problem is more pronounced when momentum-dependent interactions are included in the calculations. Many attempts reported in the literature tried to solve this problem by controlling various technical parameters like using (i) covariant treatment of two-body interaction and scattering (ii) cooling procedure via Pauli blocking and (iii) implementation of different ground-state initializations
