Phys. Rev. Lett. 78, 1018–1021 (1997)Angular Correlations for the 12C(e,e′n)11C Reaction in the Giant Resonance RegionReceived 9 July 1996; published in the issue dated 10 February 1997 Angular correlations for the 12C(e,e′n)11C reaction in the giant resonance region have been measured for forward scattering at an effective momentum transfer of 0.35 fm-1. The angular correlation for the ground-state transition indicates a strong forward-backward asymmetry at the peak of the giant dipole resonance (ω = 22.5 MeV), which is different from the nearly symmetric angular correlations observed for the 12C(e,e′p0)11B reaction. Recent random-phase approximation predictions fail to reproduce the experimental angular correlations for both (e,e′n0) and (e,e′p0), predicting the opposite patterns to those observed. © 1997 The American Physical Society URL:
