We have measured radiative lifetimes of ten Th II levels by using the laser-induced fluorescence technique and branching fractions with Fourier transform spectroscopy. By combining the new branching fractions with a total of 23 lifetimes, from the present work and from measurements by Simonsen et al. ([CITE]), absolute oscillator strengths for 180 lines have been derived. Some of these new f-values reported are relevant for radioactive dating of stars.
