Abstract
Polarization effects in ensembles of atomic particles (atoms or ions), excited by an external process and undergoing collisions with slow atomic perturbers having no nuclear spin and no hyperfine structure of the quantum states, will be examined in this chapter. Using a kinetic approach, the effect of collisions in this case can be qualitatively interpreted as the transformation of an ordering of the distribution of the relative velocity vectors into an ordering of momenta of the ensemble of excited atoms.(10)
