Spin Exchange Taking into Account Hyperfine Coupling between Electron and Nuclear Spins during Collisions: II. Collisional Kinetics of Hydrogen-Like Atoms and Spin-Exchange Cross Sections for Hydrogen in the Range 0.01 -1000 K

摘要

Kinetic tensor equations are obtained that describe the evolution of polarization moments of atoms in spin-exchange collisions and take into account hyperfine coupling of the electron and nuclear spins during collisions. For hydrogen atoms, all cross sections entering the kinetic equations are calculated.
