The recent development of electrostatic devices which allow us to store keV ion beams has
launched several new kinds of investigations. We review the basic ideas behind the …

Predicted almost forty years ago, the radiation from thermally populated excited electronic
states has recently been recognised as an important cooling mechanism in free molecules …

Fast radiative cooling of anthracene was observed in a compact electrostatic storage ring by
probing the evolution of the internal energy distribution of a stored (C 14 H 10)+ molecular …

In this study, the recurrent fluorescence of naphthalene ions was investigated using an
electrostatic ion beam trap. The number of photons from the recurrent fluorescence on the D …

Radiative cooling of carbon cluster anions C 2n+ 1−(n= 3–5) is investigated using the
cryogenic electrostatic ion storage ring DESIREE. Two different strategies are applied to …

We have measured delayed ionization of laser excited C60 molecules by detection of ions in
coincidence with emitted electrons. This makes it possible to distinguish ionization of C60 …

Several small Polycyclic Aromatic Hydrocarbons (PAHs) have been identified recently in the
Taurus Molecular Cloud (TMC-1) using radio telescope observations. Reproducing the …

Fast radiative cooling of anthracene cations (C 14 H 10)+ is studied with a compact
electrostatic storage device, the Mini-Ring. The time evolution of the internal energy …

Polycyclic Aromatic Hydrocarbons (PAHs) have long been thought to be ubiquitous in the
Interstellar Medium (ISM), as evidenced by the so-called Aromatic Infrared Bands (AIBs) …

We measured the spontaneous decays of internally hot copper and silver dimer anions, Cu
2− and Ag 2−, stored in one of the two ion-beam storage rings of the Double Electrostatic Ion …
