The lithium abundance was calculated for five metal-poor red giant stars
from Li i doublet at 6707 Å by fitting the observed
high-resolution spectra with synthetic spectra. The lithium abundance
was found to be low in all stars, logɛ(Li) ≤ 1.8, confirming
lithium depletion on the red giant and asymptotic giant branch.
