Abstract :
In this paper the novel ELectron Ion scattering in a Storage ring (eA-collider) experiment that is part of the baseline of FAIR[http://www.gsi.de/fair/reports/btr.html] will be discussed in terms of future prospects in a viable physics programme[http://www.gsi.de/documents/DOC-2006-Mar-118-1.pdf, http://www.gsi.de/fair/experiments/ELISe/] that will be feasible for the first time, making use of a clean purely electromagnetic probe in conjunction with unstable secondary beams, the electron.
