Radiative electron attachment to rotating CN through dipole-bound states
Joshua Forer, Viatcheslav Kokoouline, Thierry Stoecklin
The role of a large dipole moment in rotating neutral molecules interacting with low-energy electrons is studied using an accurate {\it ab initio} approach accounting for electroni…
Unified treatment of resonant and non-resonant mechanisms in dissociative recombination: benchmark study of CH
Joshua Forer, Dávid Hvizdoš, Xianwu Jiang +3
The theoretical approach developed here treats uniformly the direct and indirect mechanisms of dissociative recombination (DR) in a diatomic ion. The present theory is based on ele…
Quantum tunneling isotope exchange reaction H2 + D- -> HD + H-
Chi Hong Yuen, Mehdi Ayouz, Eric S. Endres +3
The tunneling reaction H + D HD + H was studied in a recent experimental work at low temperatures (10, 19, and 23~K) by Endres {\it et al.}, Phys. Rev. A…
Uncertainty Estimates for Theoretical Atomic and Molecular Data
H. -K. Chung, B. J. Braams, K. Bartschat +5
Sources of uncertainty are reviewed for calculated atomic and molecular data that are important for plasma modeling: atomic and molecular structure and cross sections for electron-…
Theory of dissociative recombination of highly-symmetric polyatomic ions
Nicolas Douguet, Ann E. Orel, Chris H. Greene +1
A general first-principles theory of dissociative recombination is developed for highly-symmetric molecular ions and applied to HO and CH, which play an important r…
Formation of H by radiative association of H and H in the interstellar medium
M. Ayouz, Raphael Lopes, Maurice Raoult +2
We develop the theory of radiative association of an atom and a diatomic molecule within a close-coupling framework. We apply it to the formation of H after the low energy co…
Potential energy and dipole moment surfaces of H3- molecule
M. Ayouz, O. Dulieu, R. Guerout +2
A new potential energy surface for the electronic ground state of the simplest triatomic anion H3- is determined for a large number of geometries. Its accuracy is improved at short…
Calculation of rate constants for vibrational and rotational excitation of the H3+ ion by electron impact
Viatcheslav Kokoouline, Alexandre Faure, Jonathan Tennyson +1
We present theoretical thermally-averaged rate constants for vibrational and rotational (de-)excitation of the H3+ ion by electron impact. The constants are calculated using the mu…
Formation of the simplest stable negative molecular ion H3- in interstellar medium
V. Kokoouline, M. Ayouz, R. Guerout +3
We present the theory of radiative association of atoms and molecules, and we apply it to the (H-H) van der Waals complex. We discuss the possibility for the H ion to…
Geometrical phase driven predissociation: Lifetimes of 2^2 A' levels of H_3
Juan Blandon, Viatcheslav Kokoouline
We discuss the role of the geometrical phase in predissociation dynamics of vibrational states near a conical intersection of two electronic potential surfaces of a D_{3h} molecule…
Correlation diagrams in collisions of three identical particles
Nicolas Douguet, Juan Blandon, Viatcheslav Kokoouline
We discuss collision of three identical particles and derive scattering selection rules from initial to final states of the particles. We use either laboratory-frame, hyperspherica…
Dissociative recombination of H3+ in the ground and excited vibrational states
Samantha Fonseca dos Santos, Viatcheslav Kokoouline, Chris H. Greene
The article presents calculated dissociative recombination (DR) rate coefficients for H+3 . The previous theoretical work on H+3 was performed using the adiabatic hyperspherical ap…
Calculation of three-body resonances using slow-variable discretization coupled with complex absorbing potential
Juan Blandon, Viatcheslav Kokoouline, Francoise Masnou-Seeuws
We developed a method to calculate positions and widths of three-body resonances. The method combines the hyperspherical adiabatic approach, slow variable discretization method (To…
