Special issue on the atomic and molecular processes in the ultracold regime, the chemical regime and astrophysics

The special issue of the Journal of Physics B: Atomic, Molecular and Optical Physics focuses on the atomic and molecular processes in the ultracold regime, the chemical regime and astrophysics. Studies of bound-free transitions in molecular systems have been a staple of computational molecular physics for many decades including applications to radiative association and photodissociation processes. The theory for inelastic transitions of a rigid-rotor due to heavy-particle collisions has been formulated in the seminal work of Arthurs and Dalgarno, which has laid the foundation for related calculations up until the present day. The approach has been utilized in countless studies and motivated the development of numerous inelastic scattering computational packages.
