Longitudinal C2 form factors in sd-shell nuclei including core-polarization effect up to second order

Abstract

Coulomb form factors of C2 transitions in several selected sd-shell nuclei have been studied. Core-polarization effects are included through a microscopic theory that includes excitations from the core 1s and 1p orbits and also from 2s-1d shell to higher orbits with excitations. The second order core-polarization leads to a minor enhancement of the calculated form factor, improving the agreement with experiment.
