Spontaneous electron emission from hot silver dimer anions: Breakdown of the Born-Oppenheimer approximation
E. K. Anderson, A. F. Schmidt-May, P. K. Najeeb +8
We report the first experimental evidence of spontaneous electron emission from a homonuclear dimer anion through direct measurements of $\rm{Ag}_2^- \rightarrow \rm{Ag}_2 + \rm{e}…
Decays of excited silver cluster anions Ag, to , in DESIREE
E. K. Anderson, M. Kamińska, K. C. Chartkunchand +6
Spontaneous decays of small, hot silver cluster anions Ag, have been studied using one of the rings of the Double ElectroStatic Ion Ring ExpEriment (DESIREE). Observa…
Spontaneous decay of small copper cluster anions Cu, on long time scales
K. Hansen, M. H. Stockett, M. Kaminska +8
We have measured the spontaneous neutral particle emission from copper cluster anions (Cu, ) stored at cryogenic temperatures in one of the electrostatic ion storage r…
Dianion diagnostics in DESIREE: High-sensitivity detection of from a sputter ion source
K. C. Chartkunchand, M. H. Stockett, E. K. Anderson +14
A sputter ion source with a solid graphite target has been used to produce dianions with a focus on carbon cluster dianions, , with . Singly and doubly c…
