We determined absolute rate coefficients for the recurrent fluorescence (RF) process in C6– anions at excitation energies above the adiabatic electron attachment energy of 4.18 eV. The experiment was performed by extracting C6– ions from a sputte

Radiative electron attachment (REA) plays an important role in forming molecular anions in various astrophysical environments. In this work, we determined the rate coefficient for the formation of C6− by REA based on a detailed balance approach. C6

Merging an HD+ beam with velocity matched electrons in a heavy ion storage ring we observed rapid cooling of the rotational excitations of the HD+ ions by superelastic collisions (SEC) with the electrons. The cooling process is well described using t
