Abstract
The resonances of saturation which occur when the mode spacing is equal to the Zeeman splitting are theoretically studied for a mode spacing ≲ the natural width broadened by collisions. Two kinds of resonances occur. The first set, due to a population effect (crossing of holes), is not resolved and is unobservable. The second set, due to a Zeeman coherence effect, is well resolved since the widths of the resonances are of the order of the Hanle-effect width. These resonances are very sensitive to the relative phases of the modes.Keywords
