摘要：

The ultraviolet photoelectron spectra (UPS) of mass-selected negative gallium arsenide cluster ions in the (2-50) atom size range was measured with a photon energy of 7.9 eV. The measured photodetachment thresholds displayed a strong even/odd oscillation through the largest clusters in this range, suggesting the presence of a substantial HOMO-LUMO gap in the corresponding neutral clusters which evolves to the band gap of bulk GaAs crystals. © 1990.
