TL;DR: In this article, a merged-beams method has been employed for obtaining absolute rate coefficients for electron-ion recombination in the collision-energy range 0-140 eV, and the measured rate coefficient is dominated by strong DR resonances even at the lowest experimental energies.

TL;DR: The measurements confirm the predicted large internuclear separation of 6 a.u., and show that the ion decays by autodetachment rather than by spontaneous dissociation, revealing a large angular momentum that leads to the metastable H2- ion.

TL;DR: Using event-by-event fragment momentum spectroscopy in a storage-ring merged-beams experiment, this article found laboratory evidence that in the dissociative recombination (DR) of HCNH{sup +} with cold electrons the energetic isomer HNC is produced with a high yield, similar to that of HCN.

TL;DR: In this article, an energy-sensitive imaging detector for studying the fragmentation of polyatomic molecules in the dissociative recombination of fast molecular ions with electrons is presented, which is based on a large area of position-sensitive, double-sided Si-strip detector, whose pulse height information is read out individually.

TL;DR: In equilibrium with the low-level blackbody field, the OH^{-} rotational transition dipole moment is determined and an effective radiative temperature is found near 15 K with about 90% of all ions in the rotational ground state.
