Abstract

[Formula Presented]He[Formula Presented] cross sections were measured in parallel kinematics for recoil momenta around 260 MeV/[Formula Presented]. A Rosenbluth decomposition of the cross section was made and transverse and longitudinal spectral functions were extracted. The longitudinal spectral function is strongly quenched relative to the transverse one, the ratio of the integral of the longitudinal to transverse spectral functions over the continuum channel being [Formula Presented]. A model which takes into account final state interactions and meson exchange currents predicts a ratio of 0.43, it can therefore explain only part ot the quenching.
