Title: Electromagnetic Response of C 12 : A First-Principles Calculation

Abstract

The longitudinal and transverse electromagnetic response functions of 12 C are computed in a “first-principles” Green’s function Monte Carlo calculation, based on realistic two- and three-nucleon interactions and associated one- and two-body currents. We find excellent agreement between theory and experiment and, in particular, no evidence for the quenching of the measured versus calculated longitudinal response. This is further corroborated by a reanalysis of the Coulomb sum rule, in which the contributions from the low-lying J π = 2 + , 0 + 2 (Hoyle), and 4 + states in 12 C are accounted for explicitly in evaluating the total inelastic strength.
