Hiltunen$ Institute of Nuclear Research of Hung. Acad. Sci. (ATOMKI), Debrecen, POB 51, H-4001, Hungary $ Department of Physical Sciences, University of Oulu, FIN-90570 Oulu, Finland A new electrostatic analyzer is presented, which is capable not only to measure the energy and angular distribution of electrons ejected from ion, electron, photon – atom collision in the angular range from 0o to 180o simultaneously, but to determine electron –electron coincidences.
