Do Skyrme forces that fit nuclear matter work well in finite nuclei?

TL;DR

This paper evaluates whether Skyrme force parameterizations that fit nuclear matter properties can accurately predict finite nuclei characteristics, revealing inconsistent performance across different forces.

Contribution

It assesses the predictive power of nuclear matter-fitted Skyrme forces on finite nuclei, highlighting their varied effectiveness.

Findings

Some forces fail to reproduce finite nuclei data

No common ability among forces to predict finite nuclei properties

Passing nuclear matter constraints does not guarantee finite nuclei accuracy

Abstract

A shortlist of Skyrme force parameterizations, recently found to have passed a series of constraints relating to nuclear matter properties is analyzed for their ability to reproduce data in finite nuclei. We analyse binding energies, isotope shifts and fission barriers. We find that the subset of forces have no common ability to reproduce (or otherwise) properties of finite nuclei, despite passing the extensive range of nuclear matter constraints.
