Decays of excited silver cluster anions Ag $_{n}$ , $n = 4$ to $7$ , in DESIREE

E. K. Anderson, M. KamiÅska, K. C. Chartkunchand +6

Spontaneous decays of small, hot silver cluster anions Ag $_{n}$ , $n = 4 - 7$ have been studied using one of the rings of the Double ElectroStatic Ion Ring ExpEriment (DESIREE). Observa…

DESIREE electrospray ion source test bench and setup for Collision Induced Dissociation experiments

N. de Ruette, M. Wolf, L. Giacomozzi +7

We give a detailed description of an electrospray ion source test bench and a single-pass setup for ion fragmentation studies at the DESIREE infrastructure at Stockholm University.…

Threshold Energies for Single Carbon Knockout from Polycyclic Aromatic Hydrocarbons

M. H. Stockett, M. Gatchell, T. Chen +6

We have measured absolute cross sections for ultrafast (fs) single-carbon knockout from Polycyclic Aromatic Hydrocarbon (PAH) cations as functions of He-PAH center-of-mass collisio…

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…

The threshold displacement energy of buckminsterfullerene C $_{60}$ and formation of the endohedral defect fullerene He@C $_{59}$

M. H. Stockett, M. Wolf, M. Gatchell +3

We have measured the threshold center-of-mass kinetic energy for knocking out a single carbon atom from C $_{60}^{-}$ in collisions with He. Combining this experimental result with cl…

Mixed cationic clusters of nitrogen and hydrogen

P. Martini, F. Hechenberger, M. Goulart +3

The addition of small impurities, such as a single proton charge carrier, in noble gas clusters has recently been shown to have considerable effects on their geometries and stabili…

Spontaneous decay of small copper cluster anions Cu $_{n}^{-}$ , $n = 3 - 6$ 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 $_{n}^{-}$ , $n = 3 - 6$ ) stored at cryogenic temperatures in one of the electrostatic ion storage r…

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…
