Abstract

The reaction of alkali (Na, Cs) clusters with water clusters embedded in helium nanodroplets is studied using femtosecond photo-ionization as well as electron impact ionization. Unlike Na clusters, Cs clusters are found to completely react with water in spite of the ultracold helium droplet environment. Mass spectra of the Cs $_n$ +(H $_2$ O) $_m$ reaction products are interpreted in terms of stability with respect to fragmentation using high-level molecular structure calculations.
