The injection of fast (1-100 keV) Li(0) diagnostic beams into magnetically confined fusion plasmas causes collisionally induced LiI emission at 670.8 nm, the intensity of which is related to the plasma (electron) density. A numerical method for quantitative reconstruction of absolute radial plasma densities from raw LiI 670.8 nm diagnostic data has been developed, which takes account of all relevant collisional interactions of the Li atoms with plasma constituents. The applicability of this method is illustrated using experimental results from the TEXTOR and ASDEX tokamak plasma discharges.
