Toward a Global Dispersive Optical Model for the Driplines

TL;DR

This paper develops a dispersive optical model for calcium isotopes, accurately describing scattering and bound states, and aims to extend this approach toward nuclei at the driplines with additional experimental data.

Contribution

It introduces a dispersive optical model analysis for calcium isotopes that effectively describes scattering and bound states, and explores extrapolation toward the driplines.

Findings

Potentials accurately describe scattering and bound states.

Model extrapolates well to other stable nuclei.

Further experiments needed for dripline predictions.

Abstract

A dispersive-optical-model analysis has been performed for both protons and neutrons on 40,42,44,48Ca isotopes. The fitted potentials describe accurately both scattering and bound quantities and extrapolate well to other stable nuclei. Further experimental information will be gathered to constrain extrapolations toward the driplines.
