The prospect of cooling matter down to temperatures that are close to absolute zero raises
intriguing questions about how chemical reactivity changes under these extreme conditions …

Molecular collisions are of fundamental importance in understanding intermolecular
interaction and dynamics. Its importance is accentuated in cold and ultra-cold collisions …

Collisions between cold polar molecules represent a fascinating research frontier but have
proven hard to probe experimentally. We report measurements of inelastic cross sections for …

Scattering between atomic and/or molecular species can be controlled by manipulating the
orientation or alignment of the collision partners. Such stereodynamics is particularly …

We report a new full-dimensional potential energy surface (PES) for the inelastic scattering
between ro-vibrationally excited H2 molecules. The new PES is based on 39,462 multi …

Energy transfer between vibrational modes can be quite facile, and it has been proposed as
the dominant mechanism for energy pooling in extreme environments such as nonthermal …

In this Perspective, we review our recent work on rotationally inelastic collisions of highly
vibrationally excited NO molecules prepared in single rotational and parity levels at v= 10 …

A crossed molecular beam, velocity-map ion-imaging apparatus has been used to
determine differential cross sections (DCSs), as a function of collider final internal energy, for …

One of the most important parameters in a collision is the 'miss distance'or impact parameter,
which in quantum mechanics is described by quantized partial waves. Usually, the collision …

High-resolution measurements of angular scattering distributions provide a sensitive test for
theoretical descriptions of collision processes. Crossed beam experiments employing a …
