We discuss the interpretation of delayed electron emission from excited clusters as a
statistical process analogous to thermionic emission from a hot filament. We argue that …

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 …

Fullerenes have recently been detected in various circumstellar and interstellar
environments, raising the question of their formation pathway. It has been proposed that they …

Recently, the presence of fullerenes in the interstellar medium (ISM) has been confirmed
and new findings suggest that these fullerenes may possibly form from polycyclic aromatic …

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 …

We report conclusive evidence of an efficient cooling mechanism via the electronic radiative
transitions of hot small molecular anions isolated in vacuum. We stored C 6-and C 6 H-in an …

The radiative cooling rates of C clusters (N= 9, 11, 12, 17–27) have been measured in the
ultrahigh vacuum of an electrostatic storage ring to values on the order of 104 s− 1. The …

Recurrent fluorescence (RF) from isolated carbon clusters containing between 24 and 60
atoms is theoretically investigated as a function of internal energy, cluster size, and structural …

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 …
