Energy-transfer quantum dynamics of HeH+with He atoms: Rotationally inelastic cross sections and rate coefficients
(American Institute of Physics Inc., 2021-02-04)
Two different ab initio potential energy surfaces are employed to investigate the efficiency of the rotational excitation channels for the polar molecular ion HeH+ interacting with He atoms. We further use them to investigate ...
HeH+Collisions with H2: Rotationally Inelastic Cross Sections and Rate Coefficients from Quantum Dynamics at Interstellar Temperatures
(American Chemical Society, 2022-04-01)
We report for the first time an accurate ab initio potential energy surface for the HeH+-H2system in four dimensions (4D) treating both diatomic species as rigid rotors. The computed ab initio potential energy point values ...
