Energy and charge transfer in ionized argon coated water clusters

Popis výsledku v původním jazyce

We investigate the electron ionization of clusters generated in mixed Ar-water expansions. The electron energy dependent ion yields reveal the neutral cluster composition and structure: water clusters fully covered with the Ar solvation shell are formedunder certain expansion conditions. The argon atoms shield the embedded (H 2 O) n clusters resulting in the ionization threshold above 15 eV for all fragments. The argon atoms also mediate more complex reactions in the clusters: e.g., the charge transferbetween Ar + and water occurs above the threshold; at higher electron energies above 28 eV, an excitonic transfer process between Ar + * and water opens leading to new products Ar n H + and (H 2 O) n H + . On the other hand, the excitonic transfer fromthe neutral Ar* state at lower energies is not observed although this resonant process was demonstrated previously in a photoion- ization experiment. Doubly charged fragments (H 2 O) n H 2 + 2 and (H 2 O) 2 + n ions are observed and In- t
