Abstract

It is pointed out that atoms placed in the presence of a static magnetic field undergo shifts of their energy levels and changes in their transition probabilities. Even at quite low static magnetic field values, these effects are important and must be taken into account when considering optical pumping or absorption experiments with alkali atoms. Linear absorption experiments with /sup 85/Rb, /sup 87/Rb, and /sup 133/Cs are described, and optical frequency shifts are given for natural rubidium. It is confirmed that important changes in atomic energy levels and transition probabilities arise even at quite low magnetic fields for the n/sup 2/P states of alkali atoms.<>
