Abstract

We have measured a new electron scattering observable, the "fifth" structure function, f01′, which is the imaginary part of the transverse-longitudinal interference response. Its observation requires a longitudinally polarized beam and coincident, out-of-plane particle detection. f01′ arises from interference between reaction channels and provides an additional means for their disentanglement. In the quasielastic C12(e→,e′p) measurements reported here, f01′ is driven by the interference of the direct knockout and rescattering amplitudes.
