Measurements of oscillator strenghts in Zr II and Cr II
Experimental oscillator strenghts (f-values) for lines in Zr II and Cr II have been determined using branching fractions (BFs) and radiative lifetimes. Experimental log gf-values for 263 spectral lines in Zr II have been derived by combining previously measured lifetimes with new BFs measured on the Lund UV Fourier Transform Spectrometer (FTS). The oscillator strengths have been used to determine
