Summary
We have applied the technique of collinear fast-ion-beam laser spectroscopy to measure the hyperfine structure (hfs) in Sc II, Tm II and N/sub 2//sup +/. Laser induced fluorescence was observed from a 50 keV ion beam which was superimposed with the output of an actively stabilized ring dye laser (rms bandwidth <1 MHz). Hyperfine measurements were made in the metastable 3d/sup 2/ and the excited 3d4p configuration of Sc II and in the 4f/sup 13/6s and 4f/sup 13/5d configurations of the Tm II. The fine and hyperfine structure of N/sub 2//sup +/ has been observed in the (0,1) and (1,2) band of B/sup 2/..sigma../sub u//sup +//minus/X/sup 2/..sigma../sub g//sup +/ system. Higher resolution measurements of the metastable 3d/sup 2/ configuration in Sc II were also made by laser-rf double resonance. The experimental results will be compared with those obtained by multiconfiguration Hartree-Fock ab-initio calculations. 15 refs., 4 figs., 5 tabs.
