description

Abstract State-selective collisional ionization of fast atomic beams is used to detect optical pumping. Counting of these ions is superior in sensitivity by several orders of magnitude to the conventional fluorescence detection, provided that the energy levels involved in the optical pumping process are sufficiently well separated. A straightforward application is envisaged in the collinear laser-fast-beam spectroscopy of rare-gas isotopes far from stability of which only very weak beams are available from on-line isotope separators.
