Neutrino-bound di-neutrons as an exotic metastable atom

TL;DR

This paper explores the theoretical possibility of a new exotic metastable atom called dineutroneum, composed of two neutrons and a neutrino, which could form under specific nuclear reactions and has estimable physical properties.

Contribution

It introduces the concept of dineutroneum as a metastable bound state of neutrons and a neutrino, providing estimations of its mass, size, and lifetime, and suggesting its formation in deuteron-electron reactions.

Findings

Dineutroneum can exist as a metastable bound state.

Estimated mass, size, and lifetime of dineutroneum.

Potential formation in deuteron-electron reactions.

Abstract

It is shown the possibility of existence of metastable atoms of dineutroneum as a bound state of two neutrons and one neutrino. Such atoms can appear in a reaction of deuterons with free or quasi-free electrons. The estimation of mass, size and lifetime of dineutroneum atom is fulfilled.
