Three-nucleon forces in exotic open-shell isotopes

TL;DR

This paper discusses the implementation of three-nucleon forces within the self-consistent Green's function approach, providing new insights into binding energies and spectral functions of exotic open-shell isotopes, and comparing theoretical results with experimental data.

Contribution

It introduces the extension of the Green's function method to include three-nucleon forces and Gorkov formalism for medium-mass open-shell nuclei.

Findings

Accurate binding energy calculations for nitrogen and fluorine isotopes.

Spectral functions of 22O match experimental observations.

Separation energy spectra of argon isotopes agree with one-neutron removal experiments.

Abstract

Advances in the self-consistent Green's function approach to finite nuclei are discussed, including the implementation of three-nucleon forces and the extension to the Gorkov formalism. We report results on binding energies in the nitrogen and fluorine isotopic chains, as well as spectral functions of 22O. The application to medium-mass open-shell systems is illustrated by separation energy spectra of two argon isotopes, which are compared to one-neutron removal experiments.
