Mutual neutralization of C $_{60}^{+}$ and C $_{60}^{-}$ ions: Excitation energies and state-selective rate coefficients

Michael Gatchell, Raka Paul, MingChao Ji +6

Context: Mutual neutralization between cations and anions play an important role in determining the charge-balance in certain astrophysical environments. However, empirical data fo…

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…

Precision measurements on Si-

J. Karls, H. Cederquist, N. D. Gibson +12

High-precision measurements of the electron affinities (EA) of the three stable isotopes of silicon, $^{28}$ Si, $^{29}$ Si and $^{30}$ Si, have been performed at the cryogenic electr…

Stability of C $_{59}$ Knockout Fragments from Femtoseconds to Infinity

Michael Gatchell, Naemi Florin, Suvasthika Indrajith +9

We have studied the stability of C $_{59}$ anions as a function of time, from their formation on femtosecond timescales to their stabilization on second timescales and beyond, using…
