On The Structure of A=3 Nuclei

TL;DR

This paper proposes a new nucleonic wavefunction model to explain the charge distribution hole in A=3 nuclei, specifically $^3{ ext He}$, without invoking quark degrees of freedom.

Contribution

It introduces a novel nucleonic wavefunction that accounts for the charge distribution hole solely within nucleonic degrees of freedom, challenging the need for quark-based explanations.

Findings

New wavefunction successfully models the charge hole in $^3{ ext He}$

Eliminates the necessity of quark degrees of freedom for this phenomenon

Provides a nucleon-based explanation for A=3 nuclear structure

Abstract

The hole in the charge distribution of $^3{\text He}$ is a major problem in A=3 nuclei. The canonical wavefucntion of A=3 nuclei which does well for electromagnetic properties of A=3 nuclei fails to produce the hole in A=3 nuclei. The hole is normally assumed to arise from explicit quark degree of freedom. Very often quark degrees of freedom are imposed to propose a different short range part of the wavefunction for A=3 to explain the hole in $^3{\text He}$. So an hybrid model with nucleonic degree of freedom in outer part and quark degrees of freedom in the inner part of the nucleus have been invoked to understand the above problem. Here we present a different picture with a new wavefunction working at short range within nucleonic degrees of freedom itself. So the above problem is explained here based entirely on the nucleonic degree of freedom only.
