Radiative lifetimes, branching fractions and oscillator strengths of some odd-parity levels in Ru I

Research output: Contribution to journalArticle


Radiative lifetime measurements have been performed for six odd-parity levels of Ru I using a time-resolved laser-induced fluorescence technique. Branching fractions of seven odd-parity levels were also measured using a grating spectrometer with a hollow-cathode lamp. The results of lifetimes and branching fractions obtained here are combined to determine the absolute oscillator strengths of 25 lines for Ru I. The obtained results are compared with previous results when available.
