On the origin of nuclear clustering

TL;DR

This paper explores the origin of nuclear clustering, suggesting it results from the openness of nuclear systems, and investigates this through the behavior of exceptional points in specific isotopes.

Contribution

It proposes that nuclear clustering arises from system openness and analyzes this through the study of exceptional points in ^16Ne and ^24S.

Findings

Clustering linked to nuclear system openness

Exceptional points influence near-threshold behavior

Insights into nuclear structure phenomena

Abstract

Clustering is one of the most complex phenomena known to the structure of atomic nuclei. A comprehensive description of this ubiquitous phenomenon goes beyond standard shell model and cluster model frameworks. We argue that clustering is a consequence of an openness of the nuclear many-body system. To illustrate this point, we study the near-threshold behavior of exceptional points in ^16 Ne and ^24 S.
