Abstract Clusters of aluminum atoms solvated with water molecules, Al(H2O) n , have been studied by one-photon ionization and time-of-flight mass spectroscopy. Characteristic feature is observed in the photoionization mass spectrum: The intensities of the product Al+(H2O) n ions are about one order of magnitude larger forn≤4 than forn≥5. The ionization potentials are determined forn up to 4. The obtained results are discussed in connection with the recent theoretical works. The photodissociation spectroscopy has also been applied to the Al+(H2O) n ions withn=1−10. The observed spectra are ascribed to the transition localized on the Al+ ion on the analogy of the results of Mg+(H2O) n photodissociation. The dissociation dynamics is also discussed from the fragmentation pattern with the aid of the recent theoretical work on the structure and stability of these ions.
