Coulomb Sums and Modification of Nucleons in The Atomic Nucleus

TL;DR

This paper investigates Coulomb sums at high momentum transfer, proposing a model where some nucleons are modified within the nucleus, aligning calculations with experimental data and estimating properties of modified nucleons.

Contribution

It introduces a novel approach linking nucleon modification in nuclei to Coulomb sum measurements, providing estimates for the modified proton's radius and nuclear matter density thresholds.

Findings

Agreement between model calculations and experimental Coulomb sums for q > 2 fm^(-1)

Estimated radius of a modified proton within the nucleus

Identification of nuclear matter density threshold for nucleon modification

Abstract

Experimental values of Coulomb sums for q > 2 fm^(-1) are considered. Assuming that a part of nucleons is modified in the nucleus, an approach is offered, in the framework of which the calculation is in agreement with the experimental data. It gives the nuclear matter density value, above which the nucleon changes its properties. The radius of a modified proton is estimated, the possibilities for a further investigation into its properties are discussed.
