Anomalous delta-type electric and magnetic two-nucleon interactions

TL;DR

This paper proposes anomalous delta-type electric and magnetic interactions between nucleons to explain the unique binding of the deuteron and the lack of other bound nucleon pairs.

Contribution

It introduces a novel class of delta-type interactions that account for specific nucleon-nucleon binding phenomena not explained by existing models.

Findings

Explains the stability of the deuteron

Accounts for the absence of other bound states

Proposes a new interaction mechanism

Abstract

Anomalous delta-type interactions, of both electric and magnetic nature, are introduced between the overlapping peripheral structures of the nucleons, which may explain the spin-triplet deuteron state and the absence of other nucleon-nucleon bound states.
