  1. Zeeman effect HFS and isotope shift

  2. 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
