New method for extracting quasi-bound states from the continuum

TL;DR

This paper introduces a novel, parameter-free approach to identify quasi-bound states within the continuum in the continuum shell model, enhancing the understanding of single-particle resonances.

Contribution

It presents a new method for extracting quasi-bound states from the continuum, generalizing weakly bound states without requiring additional parameters.

Findings

Successfully identifies quasi-bound states embedded in the continuum.

Provides a natural extension of weakly bound single-particle states.

Enhances the continuum shell model's capability to treat resonances.

Abstract

A new parameter-free method is proposed for treatment of single-particle resonances in the real-energy continuum shell model. This method yields quasi-bound states embedded in the continuum which provide a natural generalization of weakly bound single-particle states.
