摘要：
We report a rapid increase in the propensity of D2O molecules to incorporate into (H2O)n- clusters upon collisions between D2O and a distribution of (H2O)n-, 6 < n < 25, clusters. We interpret this effect by invoking a size-dependent associative electron detachment cross section which increases rapidly for n < 15. The implications of this detachment process on the "magic numbers" in the (H2O)n- distribution are discussed.
