[en] The solar photospheric abundance of ruthenium is revised on the basis of a new set of oscillator
strengths derived for Ru I transitions with wavelengths in the spectral range 2250–4710 Å. The
new abundance value (in the usual logarithmic scale where the solar hydrogen abundance is equal to 12.00), ARu = 1.72 ± 0.10, is in agreement with the most recent meteoritic result, ARu = 1.76 ± 0.03. The accuracy of the transition probabilities, obtained using a relativistic Hartree–Fock model including core-polarization effects, has been assessed by comparing the
theoretical lifetimes with previous experimental results. A comparison is also made with new measurements performed in this work by the time-resolved laser-induced fluorescence
spectroscopy for 10 highly excited odd-parity levels of Ru I
