“…He S are considered to be polarized before collision, which can be realized, for example, by extraction of the helium atoms from the plasma exposed to optical pumping by circularly polarized light [4].

In the present work, slow atomic collisions with changes of atomic spins are examined. In this case, the electron spin exchange in the process of collisions causes the polarization characteristics of atoms to change. Formalism has been constructed based on the adiabatic approximation and polarization operator technique for a description of changes of arbitrary spins of colliding atoms. Singlet-triplet transitions, analogous to those of inelastic exchange electron scattering on two-electron atoms, are described for collisions of hydrogen and alkali metal (H, K, Na, Cs, and Rb) atoms with two-electron atoms or ions (He, Li + , and Hg).

In the present work, a pattern of spin polarization is investigated within the framework of nonrelativistic interactions of electrons of colliding atoms. The electron spin exchange in the process of collision causes the polarization characteristics of atoms to change. It is demonstrated that results of collision of hydrogen atoms with alkaline metals (H, K, Na, Cs, and Rb) are analogous to those of elastic exchange electron scattering by singleelectron atoms.
