Negative ion formation in small carbon clusters

Conference ·
OSTI ID:10163267
Laser ablation of graphite into a rare gas supersonic jet has been used to generate C{sub m} clusters (both neutral and ionic) in the size range m {le} 30. Negative ions produced by three different mechanisms have been studied: (1) ion formation during the ablation process, (2) low energy electron attachment (Rydberg electron transfer) to neutral clusters, and (3) charge transfer from ground state rubidium atoms to neutral clusters. The C{sub m}{sup {minus}} distributions observed for the three cases are distinctly different, providing insights into the structures, stabilities, and electron attachment dynamics of small carbon clusters.
