Abstract
High-resolution laser spectroscopy has been performed using a tunable diode laser to measure the hyperfine structure (hfs) and Zeeman shift of two transitions in Y I. The hfs constants A of 89Y were determined for the 4d5s22D3/2 and 2D5/2 levels, and 4d5s5p4F3/2 and 4F5/2 levels; the A values of the 4F3/2 and 4F5/2 were determined for the first time. Using circular polarizations, the Zeeman spectra were selectively measured and the g factors were determined for the 4d5s5p4F3/2 and 4F5/2 levels.
