Atomic and molecular collisions is a research area focused on the dynamics of interactions between atoms, molecules, ions, and electrons over a wide range of energies, from ultracold to relativistic regimes. It investigates elastic, inelastic, and reactive scattering processes, including energy transfer, excitation, ionization, charge transfer, and chemical reaction pathways. The field combines quantum scattering theory, potential energy surface calculations, and semiclassical or fully quantum dynamical methods with beam, trap, and plasma experiments. Applications span astrophysics, atmospheric and plasma physics, fusion research, radiation damage, and controlled chemistry, providing benchmark data for cross sections, rate coefficients, and collisional models used in simulations of complex many-body systems.
Researchers from Tokyo Metropolitan University have succeeded in detecting laser-assisted electron scattering (LAES) using circularly polarized light for the first time. The use of circularly polarized light promises valuable ...
