Δ(Li) = log (X(Li)MS/X(Li)ini) vs. the corresponding values for oxygen (left panel) and sodium (right panel), for the 47Tuc best match synthetic sample with Yaccr = 0.278, (X(O)accr/ X(O)ini) = 0.1 and (X(Na)accr/ X(Xa)ini) = 3. The observed Li, O and Na abundances are also displayed (symbols with error bars), shifted to match the mean values of Δ(Li), Δ(O), and Δ(Na).
