Cesium belongs to the alkali metals; during the P -> S transition in atomic cesium, a wide doublet is emitted, consisting of two lines: l1 = 0.456 μm and l2 = 0.459 μm. Find the splitting of the terms of this doublet in a magnetic field. In this case, what formulas describe the splitting of lines in a magnetic field with induction B = 3 T: formulas for simple or complex Zeeman effects?
