Abstract
The intensity-calibrated spectra of W II have been recorded in the spectral interval 23 000-51 300 cm(-1) (1950-4350 angstrom), using the FT500 UV Fourier Transform Spectrometer at Lund Observatory. Combining the intensity data in this work with lifetimes previously measured using the time-resolved laser-induced-fluorescence (TR-LIF) technique resulted in transition probabilities and log gf values for 95 transitions in W II, originating from nine different upper levels with energies between 47 179 and 55 392 cm(-1). Of these transitions, 85 have never been measured before. The new data are compared with theoretical calculations and with previously measured values when available.
