Cold collisions of complex polyatomic molecules [PDF]
The Journal of Chemical Physics, 2012 We introduce a method for classical trajectory calculations to simulate collisions between atoms and large rigid asymmetric-top molecules. We investigate the formation of molecule-helium complexes in buffer-gas cooling experiments at a temperature of 6.5 K for molecules as large as naphthalene.

Potential energy surface of Li–O2 system for cold collisions
, 2023 This paper explores the interactions between Li and oxygen in their van der Waals state for the study of cold collisions between these two species. The quartet surface was calculated using a basis set converged spin-restricted CCSD(T) method, while for ...

Molecular vibration in cold-collision theory [PDF]
Physical Review A, 2002 Cold collisions of ground state oxygen molecules with Helium have been investigated in a wide range of cold collision energies (from 1 $μ$K up to 10 K) treating the oxygen molecule first as a rigid rotor and then introducing the vibrational degree of freedom. The comparison between the two models shows that at low energies the rigid rotor approximation

A compact design for a magnetic synchrotron to store beams of hydrogen atoms
New Journal of Physics, 2015 We present a design for an atomic synchrotron consisting of 40 hybrid magnetic hexapole lenses arranged in a circle. We show that for realistic parameters, hydrogen atoms with a velocity up to 600 m s ^−1 can be stored in a 1 m diameter ring, which ...

Direct observation of swap cooling in atom–ion collisions
New Journal of Physics, 2021 Collisions with cold particles can dissipate a hot particle’s energy and therefore can be exploited as a cooling mechanism. Kinetics teach us that cooling a particle down by several orders of magnitude typically takes many elastic collisions as each one ...

Cold collisions catalyse conformational conversion [PDF]
Physical Chemistry Chemical Physics, 2007 We have determined the abundance of two different conformational structures of the mixed benzene dimer (C(6)H(6))(C(6)D(6)) in a molecular beam, with various carrier gases. These two T-shaped conformers have a subtle zero-point energy difference of only a few cm(-1), and a transition state barrier of about 64 cm(-1).

Strong and weak cold pool collisions [PDF]
, 2022 2022 Spring.Includes bibliographical references.Collisions between convective cold pools commonly initiate new convective storms. This occurs through enhancements to the vertical velocity through mechanical forcing, and increased water vapor content via ...

Reactive collisions in confined geometries
New Journal of Physics, 2015 We consider low energy threshold reactive collisions of particles interacting via a van der Waals potential at long range in the presence of external confinement and give analytic formulas for the confinement modified scattering in such circumstances ...

Energy-energy correlators in p-Pb collisions at ALICE [PDF]
EPJ Web of ConferencesJet substructure is a powerful tool for testing QCD in elementary particle collisions. The two-point energy-energy correlator (EEC), defined as the energy-weighted cross section of particle pairs inside jets, is a novel jet-substructure observable ...
