C Longitudinal and Transverse Nuclear Electromagnetic Response Functions from all Electron Scattering Measurements on Carbon*

We report on an extraction of the ¹²C Longitudinal  (R_L) and Transverse (R_T) nuclear electromagnetic response functions from  an analysis of all available electron scattering dats on carbon. The response functions are extracted for a large range of energy transfer ν  (spanning the nuclear excitation, quasielastic,  and △(1232 MeV) region over a large range of  the square of the four-momentum transfer Q²  (02<0.5 GeV²). We extract   R_L and R_T as a  function of ν for both  fixed values of Q² as well fixed values momentum transfer  q. The data sample consists of  more than  10,000 ¹²C  differential  electron scattering and photoproduction cross section measurements. Since  the extracted response functions cover a large range of  Q² and ν, they can be used to validate nuclear models as well  Monte Caro generators for electron and neutrino scattering experiments.
