A compact source which produces atomic alkali-metal beams in individual hyperfine sublevels has been developed. The methods are demonstrated with /sup 23/Na atoms. Initially nearly all atoms are transferred into one hyperfine sublevel (Vertical BarF,m/sub F/> = Vertical Bar2,2>) by a double-resonance technique using laser-optical pumping and rf transitions. Subsequently the other hyperfine sublevels can be populated selectively by an adiabatic high-frequency transition. The hyperfine sublevel populations are determined by laser-induced fluorescence spectroscopy in a magnetic field.
