Abstract
We have measured transition frequencies, isotope shifts, and hyperfine-structure splittings in the transitions in stable ions for using collinear laser spectroscopy. Ions were generated by laser ablation in a buffer-gas atmosphere and extracted into vacuum through a nozzle and a pair of radio-frequency funnels. The results obtained are of interest as reference values for on-line measurements of short-lived titanium isotopes and for astrophysical searches for temporal or spatial variations of the fine-structure constant using quasar absorption spectra.
