Lifetimes, Branching Fractions, and Oscillator Strengths of Doubly Ionized Tungsten
M Schultz-Johanning, R Kling, R Schnabel, M Kock, ZZ Li, H Lundberg, S Johansson
A first set of W III oscillator strengths has been obtained from combined lifetime and brancing fraction measurements. The branching fractions in the wavelength region of 154-334 nm were measured on a Penning discharge with Fourier transform spectroscopy. Three levels have been calibrated on absolute scales with lifetimes measured with the time -resolved laser-induced fluorescence technique. The f-values derived have uncertainties of about 10% at best. A comparison with Cowan-code calculations is given since no other data are available in the literature.
