Lithium abundance, A(Li) (top panel), [Na/O], and [Li/Na] abundance ratios (middle and bottom panels) in our TO stars in 47 Tuc, plotted versus radial distance from the cluster center, r/rh (rh = 174′′ is the half-mass radius of 47 Tuc, Trager et al. 1993). Solid lines are linear best fits to the data in the full sample of 101 stars. Large open circles are averages obtained in 1′ wide bins.
