    "abstract": "Based on ab initi and density-functional theory calculations, an empirical\npotential is proposed to model the interaction between a fullerene molecule and\nmany sodium atoms. This model predicts homogeneous coverage of C_60 below 8 Na\natoms, and a progressive droplet formation above this size. The effects of\nionization, temperature, and external electric field indicate that the various,\nand apparently contradictory, experimental results can indeed be put into\nagreement.",
