Query: Vibrational quenching and reactive processes of weakly bound molecular
  ion-atom collisions at cold temperatures   We present a study of vibrational quenching and chemical processes of
molecular ions immersed in an ultracold atomic gas by means of the
quasi-classical trajectory (QCT) method. In particular, BaRb$^+(v)$ + Rb
collisions are studied at cold temperatures revealing a highly efficient energy
transfer between the translational degrees of freedom and internal degrees of
the molecular ion. Thus leading to a large vibrational quenching cross section
which follows the Langevin capture model prediction. These results play a key
role on the understanding of relaxation phenomena of cold molecular ions in
ultracold gases as well as in the fate of the molecules emerging trough
ion-neutral-neutral three-body recombination in an cold and dense environment.
