A renewed interest in Accelerator Mass Spectrometry (AMS) from nuclear physics laboratories is emerging in connection with Radioactive Ion Beams (RIBs). At the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL) we

Isobar separation at low energy in accelerator mass spectrometry

Autor: J.P Doupé, I. Tomski, A.E. Litherland, X.-L. Zhao

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. :323-327

The use of ion reactions at keV and eV energies for atomic or molecular isobar separation with applications in accelerator mass spectrometry (AMS) is discussed briefly. It is shown that by a combination of techniques, isobar suppression may be extend

Ion reactions for isobar separation in accelerator mass spectrometry

Autor: J.P Doupé, A.E. Litherland, I. Tomski

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 204:720-724

The use of resonant and near resonant keV ion reactions for isobar separation in AMS is discussed. It is shown that these and other ionic reactions can be useful provided that the multiple scattering is taken into account.

Ion preparation systems for atomic isobar reduction in accelerator mass spectrometry

Autor: J.P Doupé, R.P. Beukens, J.S.A. Krestow, A. E. Litherland, I. Tomski, X.-L. Zhao, William E. Kieser

Publikováno v: AIP Conference Proceedings.

Methods for carrying out isobar reduction, at or near the ion source, are reviewed. These range from charge changing and electron transfer reactions at keV energies to ion reactions with molecules at a few eV. All of these methods can emphasize parti
