Isospin dependent properties of asymmetric nuclear matter

TL;DR

This paper investigates how the symmetry energy of asymmetric nuclear matter depends on density, using a systematic approach with the M3Y interaction, and finds results consistent with recent experimental constraints.

Contribution

It provides a comprehensive analysis of isospin-dependent properties of nuclear matter using density-dependent M3Y interactions, aligning theoretical predictions with experimental data.

Findings

Incompressibility $K_ inf$ matches experimental constraints.

Isospin-dependent incompressibility $K_{asy}$ agrees with data.

Slope parameter $L$ is consistent with empirical measurements.

Abstract

The density dependence of nuclear symmetry energy is determined from a systematic study of the isospin dependent bulk properties of asymmetric nuclear matter using the isoscalar and the isovector components of density dependent M3Y interaction. The incompressibility $K_\infty$ for the symmetric nuclear matter, the isospin dependent part $K_{asy}$ of the isobaric incompressibility and the slope $L$ are all in excellent agreement with the constraints recently extracted from measured isotopic dependence of the giant monopole resonances in even-A Sn isotopes, from the neutron skin thickness of nuclei and from analyses of experimental data on isospin diffusion and isotopic scaling in intermediate energy heavy-ion collisions. This work provides a fundamental basis for the understanding of nuclear matter under extreme conditions, and validates the important empirical constraints obtained from recent experimental data.
