Negative ion production by endoergic charge transfer from fast alkali atoms to a crossed molecular beam of hydrogen halide clusters, (HX)n, has been studied for HF, HCl, HBr, HI, and mixed HF, HBr clusters. Cluster ions corresponding to n up to the order of 10 are readily detected, although the unit mass resolution required for full identification is only feasible for small clusters (masses ≤100 amu). Dissociative attachment to form the "solvated" halide or bihalide anions, [X(HX)]n-1-, is the predominant process. No evidence is found for any intact (HX)n- ions.
