Reaction Mechanism For C-12(E,E(')N)C-11 In The Continuum Above The Giant Resonance

Out-of-plane measurements of the angular correlations for the C-12(e,e'n)C-11 reaction have been performed in the continuum above the giant resonance. The cross sections were directly separated into the longitudinal and transverse, longitudinal-transverse, and transverse-transverse components. Recent random-phase approximation (RPA) predictions reproduce fairly well the angular correlations of both the C-12(e,e'n(0,1)) and C-12(e,e'p(0)) reactions, but the Hartree-Fock predictions fail to reproduce that of (e,e'n(0,1)). It suggests that RPA correlations are crucial for the interpretation of the (e,e'n(0,1)) reaction in the observed excitation energy region.
