A theoretical rate constant for the associative detachment reaction Rb((2)S) + OH(-)((1)Σ(+)) → RbOH((1)Σ(+)) + e(-) of 4 × 10(-10) cm(3) s(-1) at 300 K has been calculated. This result agrees with the experimental rate constant of 2-1 (+2)×10(-10)cm(3)s(-1) obtained by Deiglmayr et al. [Phys. Rev. A 86, 043438 (2012)] for a temperature between 200 K and 600 K. A Langevin-based dynamics which depends on the crossing point between the anion (RbOH(-)) and neutral (RbOH) potential energy surfaces… 

Reactivity of Hydrated Hydroxide Anion Clusters with H and Rb: An ab Initio Study.

This work has considered a direct and an indirect process for the electronic detachment, depending on whether water loss follows or precedes the detachment of the excess electron, of the hydrated hydroxide anion clusters and of the collisional complexes.

Cold reactive and nonreactive collisions of Li and Rb with C2− : Implications for hybrid-trap experiments

We present a theoretical investigation of cold reactive and non-reactive collisions of Li and Rb atoms with C$_{2}^{-}$. The potential energy surfaces for the singlet and triplet states of the

Associative detachment in anion-atom reactions involving a dipole-bound electron

Associative electronic detachment (AED) between anions and neutral atoms leads to the detachment of the anion’s electron resulting in the formation of a neutral molecule. It plays a key role in

Ab initio study of the neutral and anionic alkali and alkaline earth hydroxides: Electronic structure and prospects for sympathetic cooling of OH.

It is concluded that Li and K are the best candidates for an ultracold buffer gas and the 2D MOH- potential energy surfaces and the associative detachment reaction M + OH→- MOH + e-, which is the only energetically allowed reactive channel in the cold regime.

Cold collisions of ${{\rm{C}}}_{2}^{-}$ with Li and Rb atoms in hybrid traps

We present a theoretical investigation of reactive and non-reactive collisions of Li and Rb atoms with C2− molecular anions at low temperatures in the context of sympathetic cooling in hybrid trap

Cold hybrid ion-atom systems

Hybrid systems of laser-cooled trapped ions and ultracold atoms combined in a single experimental setup have recently emerged as a new platform for fundamental research in quantum physics. This paper



Translational cooling versus vibrational quenching in ultracold OH(-)-Rb collisions: a quantum assessment.

Calculations employ the coupled-channel ansatz to describe the nuclear quantum dynamics and show a very marked dependence of the inelastic cross sections and rates, at vanishing collision energies, on the initial vibrational energy content of the partner molecules.

Ionic interactions and collision dynamics in cold traps: rotational quenching of OH−(1Σ+) by Rb(2S)

A newly computed potential energy surface, which describes the forces at play between the OH− (X1Σ+) anionic molecule (treated as a rigid rotor at its equilibrium geometry) and the Rb(2S) atomic gas

Associative electron detachment: O−+H→OH+e−

Associative Electron Detachment processes are important experimental events that can readily be modeled using modern theoretical methods. Experimental methods to date have only allowed one to

High-resolution threshold photodetachment spectroscopy of OH–

Relative photodetachment cross sections for rotational thresholds of the hydroxide anion were measured using a coaxial laser-ion beam spectrometer. The thresholds correspond to transitions from the

The electron affinity of oxygen: A systematic configuration interaction approach

A sequence of configuration interaction (CI) wave functions, constructed so as to systematically approach the complete basis set, full CI limit, is used to argue that the only alternatives for

Electron detachment and charge transfer for collisions of O- and S- with H.

Associative detachment cross sections are reported for S[sup [minus]]+H[sub 2] for [ital E][lt]2 eV; the results appear to resolve an apparent discrepancy between previous measurements.

The barrier height of the F+H2 reaction revisited: coupled-cluster and multireference configuration-interaction benchmark calculations.

Large scale coupled-cluster benchmark calculations have been carried out to determine the barrier height of the F+H2 reaction as accurately as possible, and these results are used to calibrate multireference configuration-interaction calculations with empirical scaling of the correlation energy.

High resolution photodetachment from the rubidium negative ion around the Rb(5p1/2) threshold

Total and partial cross sections as well as electron angular distributions for photodetachment from Rb- have been measured with high photon energy resolution (of approximately 0.1 cm-1 or less) in
