NN Interaction JISP16: Current Status and Prospect

TL;DR

This paper reviews the development and current status of JISP16, a nonlocal NN interaction model fitted to two-nucleon and light nuclei data, emphasizing progress in ab initio calculations without three-nucleon forces.

Contribution

It introduces a new type of nonlocal NN interaction, JISP16, fitted directly to nuclear data and light nuclei properties, bypassing the need for three-nucleon forces.

Findings

Progress in ab initio NCSM calculations with JISP16

Successful description of light nuclei properties

Plans for future improvements in JISP interactions

Abstract

We discuss realistic nonlocal NN interactions of a new type - J-matrix Inverse Scattering Potential (JISP). In an ab exitu approach, these interactions are fitted to not only two-nucleon data (NN scattering data and deuteron properties) but also to the properties of light nuclei without referring to three-nucleon forces. We discuss recent progress with the ab initio No-core Shell Model (NCSM) approach and respective progress in developing ab exitu JISP-type NN-interactions together with plans of their forthcoming improvements.
