Optical pumping of the Zeeman components in the rubidium ...

The Zeeman optical pumping mechanism alters the intensity of SA peaks and it has to be considered separately for closed and open hyperfine transition peaks as well as for cross-over resonances. In the case of the closed transitions Zeeman's optical pumping causes orientation and alignment of the atoms.
