Convection Current Contributions to Spin Excitations
We first briefly review the role of convection currents in electron scattering and the utility of Rosenbluth plots in separating and studying the familiar longitudinal and transverse form factors defined for electromagnetically induced nuclear transitions. Then, noting that an energy-dependent probe-target-nucleon interaction can often be cast, to a good approximation, as an energy independent leading term plus a “convection current” dominated correction term, we study pion-nucleus and nucleon-nucleus transitions involving these “convection current” corrections. We discuss how, in both pion and nucleon-nucleus interactions, techniques that separate the (q,E,9) dependences of the nuclear response (as the Rosenbluth plot does for electron scattering) can be used to advantage.
