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.
