Abstract

Oscillator strengths for 57 U II lines in the region 3500-6700 Åhave been derived by combining new branching fraction measurements withrecently measured lifetimes. The lines combine six upper levels withnumerous low levels having excitation energies of 0-1.5 eV. The datainclude the U II line at 3859 Å, which is used forcosmochronology.
