The effect of reactant alignment on the angular distributions of scattered products in atom-molecule scattering.

New Full-Dimensional Reactive Potential Energy Surface for the H4 System

“…Due to experimental difficulties in simulating extreme conditions, energy transfer processes between two H 2 molecules (and their isotopic variants) have largely been investigated theoretically. − These calculations were carried out either in full dimensionality or within the rigid rotor approximation using various potential energy surfaces (PESs). ,− More recently, this system has been leveraged in experimental studies of cold collisions involving aligned H 2 /HD/D 2 molecules, − using the Stark-induced adiabatic Raman passage (SARP) technique . Quantum mechanical calculations by some of the authors of this paper helped to elucidate the role of shape resonances in the stereodynamics of these prototypical systems. − …”

Stereodynamical control of cold HD + D2 collisions

“…This provides a powerful approach to probe stereodynamics in collision of quantum state-prepared and aligned molecules. 65 The SARP technique has recently been extended to chemical reactions of state-prepared HD with H atoms leading to the D + H 2 product using a crossed molecular beam technique but at thermal and superthermal collision energies or collision energies above 0.5 eV. 66…”

Quantum Dynamics Studies of the Li + Na2 (V = 0, j = 0) → Na + NaLi Reaction on a New Neural Network Potential Energy Surface

“…This facilitates an opportunity to observe the complete process of the chemical reaction. The aforementioned characteristics render the ultracold reaction a frontier research subject in the field of atomic and molecular physics. − In recent years, significant experimental breakthroughs have been achieved in the field of ultracold reaction research. − To explain and guide experimental research, significant achievements have been made in theoretical research as well. − …”
