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

TL;DR

This paper investigates how the width of Gaussian wave packets affects the stability of nuclei in a semi-classical quantum molecular dynamics model, finding broader packets enhance stability across various nuclei and equations of state.

Contribution

It provides a detailed analysis of the impact of wave packet width on nuclear stability within different equations of state in quantum molecular dynamics.

Findings

Broader Gaussian wave packets improve nuclear stability.

Stability varies with different equations of state.

Nuclei remain stable throughout reactions with broader packets.

Abstract

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.
