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

Autor: Saba Zia Hassan, Jonas Tauch, Milaim Kas, Markus Nötzold, Henry López Carrera, Eric S. Endres, Roland Wester, Matthias Weidemüller

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-7 (2022)

Associative electronic detachment (AED) reactions of anions play a key role in many natural processes. Here, Hassan and colleagues investigate AED reactions between hydroxyl anions and ultracold rubidium atoms in a hybrid atom-ion trap, revealing dif

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

Autor: Jacques Liévin, Milaim Kas, Nathalie Vaeck, Jérôme Loreau

Publikováno v: The Journal of Physical Chemistry. A, 123 (41

We present a theoretical investigation of the hydrated hydroxide anion clusters, OH(H2O)n-, and of the collisional complexes, H-OH(H2O)n- and Rb-OH(H2O)n- (with n = 1-4). The MP2 and CCSD(T) methods are used to calculate interaction energies, optimiz

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

Autor: Jérôme Loreau, Jacques Liévin, Milaim Kas, Nathalie Vaeck

Publikováno v: Physical Review A. 99

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 Li--C$_{2}^{-}$ and Rb--C$_{2}^{-}$ systems have been obt

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

Autor: Jacques Liévin, Milaim Kas, Nathalie Vaeck, Jérôme Loreau

Publikováno v: The Journal of Chemical Physics, 146

We have performed a systematic ab initio study on alkali and alkaline earth hydroxide neutral (MOH) and anionic (MOH-) species where M = Li, Na, K, Rb, Cs or Be, Mg, Ca, Sr, Ba. The CCSD(T) method with extended basis sets and Dirac-Fock relativistic

Ab initio study of reactive collisions between Rb(2S) or Rb(2P) and OH−(1Σ+)

Autor: Jérôme Loreau, Milaim Kas, Nathalie Vaeck, Jacques Liévin

Publikováno v: The Journal of Chemical Physics. 144:204306

A theoretical rate constant for the associative detachment reaction Rb($^{2}S$)$+$OH$^{-}$($^{1}\Sigma^{+}$)$\rightarrow \,$ RbOH($^{1}\Sigma^{+}$)$+\,e^{-}$ of 4$\,\times$10$^{-10}$cm$^{3}$s$^{-1}$ at 300 K has been calculated. This result agrees wi

Cold collisions of C2- with Li and Rb atoms in hybrid traps

Autor: Jérôme Loreau, Milaim Kas, Jacques Liévin, Nathalie Vaeck

Publikováno v: Journal of physics. Conference series

We present a theoretical investigation of reactive and non-reactive collisions of Li and Rb atoms with C 2 − molecular anions at low temperatures in the context of sympathetic cooling in hybrid trap experiments. Based on accurate potential energy s
