Table 1: NGC 6752 stars, their atmospheric parameters and Li abundances. Stars are ordered by increasing [Na/Fe] abundances. The first three columns report the observed photometric parameters. The G01 temperature was of 6226 K and the surface gravity of log g = 4.28 for all stars. The Li value in Col. 6 and [Na/Fe] in Col. 7 are computed with these stellar parameters. Column 8 presents $T_{\rm eff}$ computed according to the Alonso scale, b-y colour and the reddening of E(b-y)= 0.032(G03). The [Na/Fe] abundances of Col. 9 and the Li abundances in Col. 10 are computed adopting the last temperatures.
