Experimental oscillator strengths in Th II
(2002) In Astronomy & Astrophysics 382(1). p.368-377- Abstract
- We have measured radiative lifetimes of ten Th II levels by using thelaser-induced fluorescence technique and branching fractions withFourier transform spectroscopy. By combining the new branching fractionswith a total of 23 lifetimes, from the present work and frommeasurements by Simonsen et al. (cite{Simonsen}), absolute oscillatorstrengths for 180 lines have been derived. Some of these new f-valuesreported are relevant for radioactive dating of stars.
