Resonance Ionization Spectroscopy in collinear geometry has been successfully applied to a fast beam of Yb atoms. The atoms were excited stepwise into a Rydberg state by pulsed laser light, ionized in an electrical field and deflected onto a secondary electron detector. The efficiency was 1 . 10(-5) detected ions per incoming atom on a background from collisional ionization of 1 . 10(-8). The technique has been exploited for the measurement of hyperfine structures and isotope shifts of unstable Yb isotopes, in particular 157Yb, 159Yb and Yb-175.
