    "abstract": "The quasielastic longitudinal electromagnetic response function R_L is\nstudied within the context of a model that extends our previous investigations\nof pionic correlations and currents. Four mesons are now employed (pion, rho,\nsigma and omega, via the Bonn potential) and the many-body dynamics are\nextended to the full random-phase approximation built upon a Hartree-Fock\nbasis. Wherever possible the Lorentz covariance of the problem is respected.\nThe first three energy-weighted moments of the reduced response are computed,\nnamely, the zeroth moment (Coulomb sum rule), the first moment (related to the\nposition of the quasielastic peak) and the second moment (related to the peak\nwidth or variance). We discuss how with a modest downward adjustment of the\nFermi momentum it is possible to obtain the expected zeroth and second moments;\nthis implies that the nuclear system has a lower density than that required\nwhen using the free relativistic Fermi gas and accordingly that the interaction\neffects are weaker than one might initially find.",
