Abstract

A systematic study of photoelectron spectroscopy for C60NaN- (N=0-33) and C70NaN- (N=0-15) clusters is reported. These clusters are produced by a laser vaporization source and their photoelectron spectrum is measured using a magnetic-bottle time-of-flight spectrometer. For N<13, the adiabatic electron affinity and the vertical detachment energy display strong regular features with increasing N. A packing of the sodium atoms in stable Na3 trimers is inferred, with each atom lying above a pentagonal ring. For larger clusters (N≥13), a very different trend is observed, signing the appearance of a metallic behavior for the sodium layer at the fullerene surface. The specific case of C70 is also discussed.
