The excess in the quasi-elastic transverse response function as measured by inclusive electron-nucleus scattering has remained a puzzle for a long time. For light nuclei, where this excess is largest, the corresponding Euclidean response functions are derived from the separated response functions obtained from the world data, and compared to those calculated with Green’s function Monte Carlo methods using realistic interactions and currents. Large contributions associated with two-body currents are found for the transverse response, in agreement with data. We find in particular that the large enhancement is only obtained if in the description of the initial (bound) and the final (continuum) state the tensor-and short range np correlations are included.
