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}…
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…
Radiative lifetimes of the bound excited states of
K. C. Chartkunchand, M. Kamińska, E. K. Anderson +20
The intrinsic radiative lifetimes of the and bound excited states in the platinum anion have be…
First storage of ion beams in the Double Electrostatic Ion-Ring Experiment - DESIREE
H. T. Schmidt, R. D. Thomas, M. Gatchell +31
We report on the first storage of ion beams in the Double ElectroStatic Ion Ring ExpEriment; DESIREE, at Stockholm University. We have produced beams of atomic carbon anions and sm…
Rotationally cold OH ions in the cryogenic electrostatic ion-beam storage ring DESIREE
H. T. Schmidt, G. Eklund, K. C. Chartkunchand +14
We apply near-threshold laser photodetachment to characterize the rotational quantum level distribution of OH ions stored in the cryogenic ion-beam storage ring, DESIREE, at St…
