Deformation effect on total reaction cross sections for neutron-rich Ne-isotopes

TL;DR

This paper investigates how nuclear deformation influences the total reaction cross sections of neutron-rich Ne isotopes scattering off carbon targets at high energy, using a combination of folding models and mean-field calculations.

Contribution

It introduces a comprehensive analysis combining the double-folding model with deformation effects from antisymmetrized molecular dynamics to explain reaction cross sections.

Findings

Deformation increases calculated reaction cross sections to match experimental data.

The model successfully reproduces isotope dependence of reaction cross sections.

Deformation effects are significant for neutron-rich Ne isotopes.

Abstract

Isotope-dependence of measured reaction cross sections in scattering of $^{28-32}$Ne isotopes from $^{12}$C target at 240 MeV/nucleon is analyzed by the double-folding model with the Melbourne $g$-matrix. The density of projectile is calculated by the mean-field model with the deformed Wood-Saxon potential. The deformation is evaluated by the antisymmetrized molecular dynamics. The deformation of projectile enhances calculated reaction cross sections to the measured values.
