Abstract
The dependence of the Li-abundance on the equivalent width of the Li-resonance doublet at λ 6708 Å is calculated for different umbral models. The choice of the model strongly influences the deduced Li-abundance (up to a factor 8 or Δ log ɛ Li = 0.9) even when using recent umbral models. Detailed discussion of the observations and reduction with the most suitable umbral model (Stellmacher and Wiehr, 1970) leads to an abundance of log ɛ Li = 1.1±0.05 (in the log ɛ H = 12.0 scale).
