Longitudinal and transverse form factors from 12C

Abstract

Electron scattering form factors from 12C 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 1s and 1p shells core orbits up to the 1f–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.
