Title Extraction of the Coulomb Sum Rule and Longitudinal Quasielastic Supression from an Analysis of Available e-12C and e-16O Cross Section Data.
Abstract We report on a phenomenological analysis of all available electron scattering data on 12C (about 8000 differential cross section measurements) and 16O (about 250 measurements) within the frame-work of the superscaling model (including Pauli blocking). All data are included down to the lowest momentum transfer ? q including photo-production. We find that, in addition to the expected enhancement of the transverse quasielastic (QE) response function (RQET ), there is ¿Extra Suppression¿ of the QE longitudinal response function (RQEL ) beyond that expected from Pauli blocking, and we extract a parameterization of the |? q| dependence of this ¿Extra Suppression¿. We additionally find that the nuclear excited states can contribute significantly (up to 30%) to the Coulomb Sum Rule SL(q). All excited states have been fully included in the analysis to provide the most accurate determination of SL(q) to date, which is compared to theoretical predictions.
