The FERRUM project: improved experimental oscillator strengths in CrII.

NILSSON H., LJUNG G., LUNDBERG H. and NIELSEN K.E.

Abstract (from CDS):

We report absolute oscillator strengths for 119 CrII transitions in the wavelength region 2050-4850Å. The transition probabilities have been derived by combining radiative lifetimes, measured with time-resolved laser induced fluorescence, and branching fractions from intensity calibrated Fouirer transform spectrometer data. New radiative lifetimes for the 3d4(5D)4p 4F, 4D and 6P terms are reported, adding up to a total of 25 energy levels with measured lifetimes used to derive this improved set of atomic data.
