Zeeman effect HFS and isotope shift

Anomalous Zeeman Effect More than three closely spaced optical lines were observed. The interaction that splits the energy levels in an external magnetic field is caused by interaction. The magnetic moment depends on The 2J + 1 degeneracy for a given total angular momentum state J is removed by the effect of the . If the is small compared to internal magnetic field, then and precess about while precesses slowly about . <= 0.1T for Zeeman splitting The normal Zeeman affect occurs for S=0 Orbital contribution and Spin magnetic moment

HFS and isotope shift

HFS levels: for Q=0 full lines B > 0 5/2 (5/2)A 3/2 (3/2)A 1/2 HFS levels: for Q=0 full lines B > 0 broken lines B < 0 with

Field isotope shift: This amounts to a few percent r charge density of s electrons at the site of the nucleus This amounts to a few percent
