Abstract
The solar abundance of lithium and its isotopic abundance ratio were determined by comparing synthetic spectra with the high quality center-to-limb spectra of the solar lithium feature presented in Paper I by Brault and Muller (1974). The following possible effects on the abundance result were considered: deviations from LTE, atmospheric models, blends by molecular and atomic lines, hyperfine structure, large scale velocity fields. It was found that the photospheric lithium abundance is logɛLi=1.0±0.1. The greatest uncertainty is due to differences in the atmospheric models. The NLTE abundance result is 0.05 dex smaller than the LTE value. A mean depth of line formation was determined for the Li7i λ16707.776 A line. The lithium isotopic abundance ratio was found to be Li6/Li7⩽0.01.
