Radiative stabilization of the indenyl cation: Recurrent fluorescence in a closed-shell polycyclic aromatic hydrocarbon

James N. Bull, Arun Subramani, Chang Liu +5

Several small polycyclic aromatic hydrocarbons (PAHs) with closed-shell electronic structure have been identified in the cold, dark environment Taurus Molecular Cloud-1. We measure…

Dissociation and radiative stabilization of the indene cation: The nature of the C-H bond and astrochemical implications

M. H. Stockett, A. Subramani, C. Liu +5

Indene (CH) is the only polycyclic pure hydrocarbon identified in the interstellar medium to date, with an observed abundance orders of magnitude higher than predicted by a…

Mutual neutralization of C and C 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, , 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, with sizes ranging from to 13, and 15. After production in a sputter ion sourc…

Stability of C Knockout Fragments from Femtoseconds to Infinity

Michael Gatchell, Naemi Florin, Suvasthika Indrajith +9

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