An electrostatic separator for heavy recoil nuclei

Abstract An electrostatic separator is described which separates evaporation residues produced in heavy ion reactions with medium heavy projectiles (e.g. 16 O) from the beam particles and fission fragments. The high charge state of the recoil nuclei, resulting from electron stripping in the target and Auger cascades following internal conversion transitions, is taken advantage of for deflection in s simple electrical condensor with a potential difference of less than 65 kV. In combination with a conversion electron spectrometer and germanium detectors, the spectroscopy of evaporation residues becomes possible also for reactions with high fission competition.
