Cooling of gold cluster anions, Au $_{N}^{-}$ , $N = 2 - 13, 15$ , in a cryogenic ion-beam storage ring

Klavs Hansen, Tian Weihao, Emma K. Anderson +9

We have measured the spontaneous and photo-induced decays of anionic gold clusters, Au $_{N}^{-}$ , with sizes ranging from $N = 2$ to 13, and 15. After production in a sputter ion sourc…

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}…

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…
