A liquid beam (continuous liquid now in a vacuum) of a calcium iodide (CaI2) solution in ethanol (EtOH) was irradiated with a 220 nm laser, and ions ejected from the surface following multiphoton ionization were observed by a time-of-flight mass spectlometer. Cluster ions, CaOEt+(EtOH)(m) (m = 2-9), CaI+(EtOH)(m) (rn = 1-7). and H+(EtOH)(m) (m = 3-5) were found to be produced. The measurement of the velocities of the product cluster ions indicates that two mechanisms an operative: ions formed on the liquid surface: are ejected with accompanying solvent molecules, and ions generated by Coulomb explosion of a divalent cluster ion, Ca2+(EtOH)(m), are repelled with gaining a sizable translational energy.
