Abstract
Angular correlations for the reaction in the giant resonance region have been measured for forward scattering at an effective momentum transfer of . The angular correlation for the ground-state transition indicates a strong forward-backward asymmetry at the peak of the giant dipole resonance , which is different from the nearly symmetric angular correlations observed for the reaction. Recent random-phase approximation predictions fail to reproduce the experimental angular correlations for both and , predicting the opposite patterns to those observed.
