Spin-Orbit Suppression of Cold Inelastic Collisions of Aluminum and Helium Please share

... Theoretical quantum calculations based on ab initio interatomic potentials have had some recent success in predicting inelastic collision rates [7,14,15]. In many atomic systems, however, the collision rates are either too fast or too slow to be directly measured, which limits the range over which t ...

Because there is a selection rule ∆S = 0 (which is not completely rigorous as we will see below), these levels (singlet, i.e. S = 0, and triplet, i.e. S = 1) are separated on the energy level diagram since only a few spectral lines result from transitions from tri ...

Population inversion

In science, specifically statistical mechanics, a population inversion occurs while a system (such as a group of atoms or molecules) exists in a state with more members in an excited state than in lower energy states. It is called an ""inversion"" because in many familiar and commonly encountered physical systems, this is not possible. The concept is of fundamental importance in laser science because the production of a population inversion is a necessary step in the workings of a standard laser.
