Abstract
The effects of the restoration of Galilei invariance in the nuclear
many-body problem on the electromagnetic properties of simple bound
states are investigated. For this purpose the form factors for elastic
electron scattering from the oscillator ground states of
,
and
as well as those for elastic and inelastic electron scattering
between various one-hole states with respect to these reference configurations
are computed with and without projection into the center-of-momentum rest
frame. It is demonstrated that, in some cases, the full restoration of
Galilei invariance produces results which are considerably different from
those obtained with the usual approximate way to treat the center-of-mass
motion. The same holds for the mathematical Coulomb sum rules and
their first and second moments obtained for the above-mentioned nuclei.
