Abstract
Through combining experimental branching fractions (BFs) with radiative lifetimes, transition probabilities and oscillator strengths of Eu I for 39 lines from 16 excited levels were derived for the first time. The energies range from 27852.90 to 41443.70 cm-1. The BFs were determined in this work using the Fourier transform spectra available from National Solar Observatory database, and the lifetimes were obtained from literature. Furthermore, BFs for 22 lines, previously reported in the literature, were also determined for comparisons. The new results reported in this work will enrich spectral database and are expected to be widely used in many fields.
