Longitudinal and Transverse Form Factors from $^{12}$C

TL;DR

This paper investigates electron scattering form factors from carbon-12 using a shell model that includes higher particle-hole configurations, resulting in a good match with experimental data across all momentum transfers.

Contribution

It introduces a shell model with extended particle-hole excitations up to the 1f-2p shell to improve form factor predictions.

Findings

Higher configurations significantly alter form factors.

Model accurately reproduces experimental data.

Extended shell model enhances understanding of nuclear structure.

Abstract

Electron scattering form factors from $^{12}$C have been studied in the framework of the particle-hole shell model. Higher configurations are taken into account by allowing particle-hole excitations from the 1$s$ and 1$p$ shells core orbits up to the 1$f-2p$ shell. The inclusion of the higher configurations modifies the form factors markedly and describes the experimental data very well in all momentum transfer regions.
