The FERRUM project: laboratory-measured transition probabilities for Cr II
J. Gurell, H. Nilsson, L. Engstrom +4
Aims: We measure transition probabilities for Cr II transitions from the z ^4H_J, z ^2D_J, y ^4F_J, and y ^4G_J levels in the energy range 63000 to 68000 cm^{-1}. Methods: Radiativ…

The FERRUM project: Transition probabilities for forbidden lines in [FeII] and experimental metastable lifetimes
J. Gurell, H. Hartman, R. Blackwell-Whitehead +5
Accurate transition probabilities for forbidden lines are important diagnostic parameters for low-density astrophysical plasmas. In this paper we present experimental atomic data f…
