Nam(H2O)n Clusters (, ) are formed in a recently build pick-up arrangement. Preformed water clusters traverse a sodium oven, where sodium atoms are picked up. At low sodium vapour pressure ( mbar) pure Na(H2O)n clusters are observed in the mass spectra. At high sodium vapour pressure ( mbar) the water cluster pick up more than 50 Na atoms and reaction products Na(NaOH)n () dominate the mass spectra. The even number of NaOH units in the products indicate that also in a finite cluster the reaction occurs in pairs as in the macroscopic reaction.
