Regularized pseudopotential for mean-field calculations

TL;DR

This paper introduces a finite-range pseudopotential with additional terms for mean-field nuclear calculations, comparing its predictions with established interactions to evaluate its effectiveness.

Contribution

It proposes a new finite-range pseudopotential with spin-orbit and density-dependent terms for mean-field nuclear models, and assesses its predictive accuracy.

Findings

Predictions for spherical nuclei binding energies are comparable to Gogny D1S results.

The pseudopotential shows promise for improved mean-field calculations.

Parameter adjustment uses a specific penalty function.

Abstract

We present preliminary results obtained with a finite-range two-body pseudopotential complemented with zero-range spin-orbit and density-dependent terms. After discussing the penalty function used to adjust parameters, we discuss predictions for binding energies of spherical nuclei calculated at the mean-field level, and we compare them with those obtained using the standard Gogny D1S finite-range effective interaction.
