The No-Core Gamow Shell Model: Including the continuum in the NCSM

TL;DR

This paper introduces the No-Core Gamow Shell Model, a novel approach that incorporates continuum effects into the No-Core Shell Model to better describe unstable nuclei and resonant states.

Contribution

It presents a new formalism combining the Gamow Shell Model with the No-Core Shell Model for the first time.

Findings

Successfully benchmarks the new approach against known cases.

Demonstrates applicability to unstable nuclei.

Provides improved descriptions of resonant and scattering states.

Abstract

We are witnessing an era of intense experimental efforts that will provide information about the properties of nuclei far from the line of stability, regarding resonant and scattering states as well as (weakly) bound states. This talk describes our formalism for including these necessary ingredients into the No-Core Shell Model by using the Gamow Shell Model approach. Applications of this new approach, known as the No-Core Gamow Shell Model, both to benchmark cases as well as to unstable nuclei will be given.
