Nuclear EoS with finite range interaction and the Constrained Dynamics

TL;DR

This paper investigates how many-body correlations influence the nuclear equation of state (EoS) and related observables like fusion-fission cross-sections, IMF production, and flow in nuclear reactions, using the Constrained Molecular Dynamics model.

Contribution

It introduces a detailed analysis of many-body correlation effects on the nuclear EoS within the Constrained Molecular Dynamics framework, highlighting their impact on reaction observables.

Findings

Correlation effects significantly alter fusion-fission cross-sections

IMF production is sensitive to correlation effects

Transversal flow depends on the treatment of correlations

Abstract

The effects of the many-body correlations with respect the MF description characterizing the Constrained Molecular Dynamics are discussed in the case of finite and zero range effective microscopic interactions. In particular, for the system $^{64}Ni+^{48}Ca$ fusion-fission cross-sections, IMF production and transversal flow have been evaluated in the framework of the CoMD model at different incident energies. The results obtained significantly depend on whether the effects of the above-mentioned correlations are taken into account in the corresponding EoS.
