Octupole deformation properties in the actinides region using Fayans functionals

TL;DR

This study uses Fayans energy density functionals to systematically analyze octupole deformation in actinide nuclei, providing accurate predictions and comparing favorably with Skyrme EDFs and experimental data.

Contribution

First comprehensive survey of octupole deformation in actinides using Fayans functionals, highlighting their predictive accuracy and consistency with other models.

Findings

Fayans EDFs predict octupole deformations similar to Skyrme-based EDFs.

Fayans EDFs accurately reproduce experimental ground state properties.

Similar trends in nuclear properties observed across different EDF models.

Abstract

In this first-of-its-kind survey conducted on heavy and deformed nuclei in the actinide region of the nuclear chart, we have charted nuclear ground state properties predicted by Fayans energy density functionals (EDFs), focusing in particularly on octupole deformability. Compared to earlier studies with Skyrme-based EDFs, we found similar region of octupole deformed nuclei. Moreover, Fayans EDFs were found to provide accurate predictions for various ground state properties, when compared to experimental data. Comparison to Skyrme-based EDF shows similar trends in various nuclear properties.
