Abstract :
Photoelectron spectra of mass-separated, negatively charged, bare and reacted aluminium clusters AlnHm− (n=12–14, m=0–2) are presented and compared to the results of corresponding calculations. A large HOMO–LUMO gap of 1.4 eV is found for the neutral Al13H cluster, indicating an extraordinarily high stability of this cluster. Adsorption of a second hydrogen atom results in the disappearance of the gap.
