Zeeman effect - Wikipedia

The Paschen–Back effect is the splitting of atomic energy levels in the presence of a strong magnetic field. This occurs when an external magnetic field is sufficiently strong to disrupt the coupling between orbital (→) and spin (→) angular momenta. This effect is the strong-field limit of the Zeeman effect.Get price
