摘要
Using a new experimental setup we have measured UV (hv = 6.4 eV) photoelectron spectra of cold silicon cluster anions Si-n in a very broad size range. For sizes up to n = 46 the spectra exhibit rich structures. For larger sizes only smooth spectra have been obtained. No trace of a bandgap has been found even for clusters with more than 1000 atoms.
