Abstract: | Electron transfer from state-selected Ar** (ns, nd) Rydberg atoms to neutral (N2O) m and (CF3Cl) m clusters has been studied for principal quantum numbersn between 10 and 45. The dominant product ions are (N2O) q ·O? and, dependent on stagnation pressure, (CF3Cl) q ·Cl? or (CF3Cl) q ·FCl?, respectively. In both cases we observe a strongn-dependence of the negative cluster ion spectra. While for lown, broad ion distributions are observed, much narrower distributions are found for highn, especially for N2O negative cluster ions around the dominant species (N2O)6·O?, corresponding to a remarkably size-selective process. Possible reasons for this behaviour are briefly discussed. |
