Abstract
Electron scattering Coulomb form factors for the single-particle quadrupole
transitions in
p-shell and
sd-shell nuclei have been studied. Core polarization
effects are included through a microscopic theory that includes excitations
from the core orbits up to higher orbits with
excitations.
The modified surface delta interaction is adopted as a residual interaction.
The results are discussed for the (
)
proton transition in
, (
)
neutron transition in
and (
)
proton transition in
. The inclusion of
core polarization effects modifies the form factors markedly and describes
the experimental data very well in both the absolute strength and the
momentum transfer dependence.
