Abstract

Abstract The deviations from the pure Rutherford scattering due to the finite quadrupole moment in the ground state has been recalculated to second order in the quadrupole moment. It is shown that for unpolarized targets the deviations are small once the excitations into higher states are taken into account. The smallness of the effect is due to a strong cancellation between the two second order terms in the perturbation expansion. This fact was not realized by the authors who dealt previously with this problem. For polarized or aligned targets the first order amplitude contributes most of the effect and deviations of the order of 10% are expected. Finally, a convenient parameterization of the deviations is presented.
