Mutual neutralisation in Li $^{+}$ +H $^{-}$ /D $^{-}$ and Na $^{+}$ +H $^{-}$ /D $^{-}$ collisions: Implications of experimental results for non-LTE modelling of stellar spectra

Paul S. Barklem, Anish M. Amarsi, Jon Grumer +6

Advances in merged-beams instruments have allowed experimental studies of the mutual neutralisation (MN) processes in collisions of both Li $^{+}$ and Na $^{+}$ ions with D $^{-}$ at energi…

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 $_{n}$ , $n = 4$ to $7$ , in DESIREE

E. K. Anderson, M. Kamińska, 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…

Dianion diagnostics in DESIREE: High-sensitivity detection of $C_{n}^{2 -}$ 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, $C_{n}^{2 -}$ , with $n = 7 - 24$ . Singly and doubly c…
