Competing Ionization and Dissociation: Extension of the energy-dependent frame transformation to the gerade symmetry of H
David Hvizdos, Roman Curik, Chris H Greene
This article solves two major tasks that frequently arise in the theory of electron collisions with a target molecular cation. First, it extends the energy-dependent frame transfor…
Autodetachment of diatomic carbon anions from long-lived high-rotation quartet states
Viviane C. Schmidt, Roman Čurík, Milan Ončák +11
Highly excited C ions prominently feature electron detachment at a mean decay time near 3 milliseconds with hitherto unexplained origin. Considering various sources of un…
Unimolecular processes in diatomic carbon anions at high rotational excitation
Viviane C. Schmidt, Roman Čurík, Milan Ončák +11
On the millisecond to second time scale, stored beams of diatomic carbon anions C from a sputter ion source feature unimolecular decay of yet unexplained origin by electron…
Competing Ionization and Dissociation in the H Gerade System
Dávid Hvizdoš, Roman Čurík, Chris H. Greene
A numerically solvable two-dimensional (2D) model, employed by the authors to study the dissociative recombination of H in the ungerade symmetry [Phys. Rev. A ,…
Energy-dependent frame transformation theory for dissociative recombination
Dávid Hvizdoš, Chris H. Greene, Roman Čurík
The energy-dependent frame transformation theory of Gao and Greene 1990 [Phys. Rev. A {\bf 42}, 6946 (1990)] is extended to yield quantitatively accurate description of the dissoci…
Dissociative recombination of cold HeH ions
Roman Čurík, Dávid Hvizdoš, Chris H. Greene
The HeH cation is the simplest molecular prototype of the indirect dissociative recombination (DR) process that proceeds through electron capture into Rydberg states of the cor…
-matrix calculations of electron collisions with lithium atom at low energies
Michal Tarana, Roman Čurík
-matrix calculations of the electron collisions with lithium atom at energies below the excitation threshold are presented. The , and phase shifts ca…
Dissociative recombination by frame transformation to Siegert pseudostates: A~comparison with a numerically solvable model
Dávid Hvizdoš, Martin Váňa, Karel Houfek +4
We present a simple two-dimensional model of the indirect dissociative recombination process. The model has one electronic and one nuclear degree of freedom and it can be solved to…
Inelastic low-energy collisions of electrons with HeH: rovibrational excitation and dissociative recombination
Roman Čurík, Chris H. Greene
Inelastic low-energy (0--1 eV) collisions of electrons with HeH cations are treated theoretically, with a focus on the rovibrational excitation and dissociative recombination (…
LiHe in the early Universe: a full assessment of its reaction network and final abundances
Stefano Bovino, Roman Curik, Daniele Galli +2
We present the results of quantum calculations based on entirely ab initio methods for a variety of molecular processes and chemical reactions involving the LiHe ionic polar mo…
Indirect Dissociative Recombination of LiH Molecules Fueled by Complex Resonance Manifolds
R. Čurík, Chris H. Greene
The LiH molecule is prototypical of the indirect dissociative recombination (DR) process, in which a colliding electron destroys the molecule through Rydberg capture pathways…
