摘要：

The first study of very low energy electron attachment to mixed water-ammonia clusters is reported here. A ''magic'' cluster anion distribution with strong similarities to that of pure water cluster anions is observed. The mixed (H2O...NH3)- dimer is created under very specific experimental conditions and its existence is a test of the theory of electron binding by a dipole. This fragile species has a very small electron binding energy as inferred from field detachment experiments.
