The a P-3(0)-y D-3(1)o Ti I transition at 592.2 nm was investigated by
using a hollow-cathode discharge. Sub-Doppler resolution was obtained
by combining optogalvanic detection with saturation spectroscopy and
the non-linear Hanle effect. The upper state Lande factor was also det
ermined by Zeeman intermodulated spectroscopy.
