Description
To measure transition probabilities for CrII transitions from the z^4^H_J_, z^2^D_J_, y^4^F_J_ and y^4^G_J_ levels in the energy range 63000 to 68000cm^-1^. Radiative lifetimes were measured using time-resolved laser-induced fluorescence from a laser-produced plasma. In addition, branching fractions were determined from intensity calibrated spectra recorded with a UV Fourier transform spectrometer. The branching fractions and radiative lifetimes have been combined to yield accurate transition probabilities and oscillator strengths. We present laboratory measured transition probabilities for 145 CrII lines and radiative lifetimes for 14 CrII levels. The laboratory measured transition probabilities are compared to the values from semi-empirical calculations and laboratory measurements in the literature.
