We developed an adiabatic theory for cold anisotropic collisions between slow atoms and cold molecules. It enables us to investigate the importance of the couplings between the projection states of the rotational motion of the atom about the molecular axis of the diatom. We tested our theory using the recent results from the Penning ionization reaction experiment (4)He(1s2s (3)S) + HD(1s(2)) → (4)He(1s(2)) + HD(+)(1s) + e(-) [Lavert-Ofir et al., Nat. Chem. 6, 332 (2014)] and demonstrated that… Expand

Adiabatic Variational Theory for Cold Atom-Molecule Collisions: Application to a Metastable Helium Atom Colliding with ortho- and para-Hydrogen Molecules.
This paper presents how the variational approach of the adiabatic theory for low-temperature collision experiments can be used for the study a 5D collision between the atom and the diatomic molecule with no limitations on its rotational quantum states and no plane restrictions. Expand
Quantum Effects in Cold Molecular Collisions from Spatial Polarization of Electronic Wave Function.
This work incorporates complex potential energy surfaces into adiabatic variational theory, thereby reducing the multidimensional scattering process to a series of uncoupled 1D scattering "gedanken experiments" and manifests that the structures in the observed reaction rate coefficient are due to the spatial arrangement of the excited He p-orbitals with respect to the interaction axis.

Communication: Importance of rotationally inelastic processes in low-energy Penning ionization of CHF3.
It is found that the broad range of collision energies combined with the relatively small rotational constants of CHF3 makes rotationally inelastic collisions a crucial player in the total reaction dynamics. Expand
Evidence of Nonrigidity Effects in the Description of Low-Energy Anisotropic Molecular Collisions of Hydrogen Molecules with Excited Metastable Helium Atoms
It is shown that the effect of nonrigidity of the H2 molecule on the resonant structure, absent in the previous study, is critical to predict the correct positions of the resonances in that case and calculated reaction rate coefficients are in remarkable agreement with the experimental data without empirical adjustment of the interaction potential.

Ultracold Rb-OH collisions and prospects for sympathetic cooling.
It is found that in cold collisions of Rb atoms with OH radicals the molecules have a strong propensity for changing their internal state, which could make sympathetic cooling of OH in a Rb buffer gas problematic in magnetostatic or electrostatic traps. Expand
Universal rate constants for reactive collisions of ultracold molecules.
A simple quantum-defect model gives analytic expressions for the complex scattering length and threshold collision rates of ultracold molecules and gives universal rate constants for s- and p-wave collisions that are independent of short-range dynamics. Expand

Observation of the isotope effect in sub-kelvin reactions.
