o Interaction between atoms and field can be classified into two regimes: o Weak fields: Zeeman effect, either normal or anomalous. o Strong fields: Paschen-Back effect. o Normal Zeeman effect agrees with the classical theory of Lorentz. Anomalous effect depends on electron spin, and is purely quantum mechanical.
5 Feb 2016 THE NORMAL (CLASSICAL) ZEEMAN EFFECT. INTRODUCTION. 1. THEORY. 2. Generation of light by charged particle motion. 2. An isotropic, hot gas and unpolarized light emission. 4. Breaking the symmetry of the gas by applying a magnetic field. 5. Harmonic oscillator with an applied magnetic field. 6.
Abstract. We first invesigate the normal Zeeman Effect of the red Cd line emerging from a gas discharge lamp in the presence of an external magnetic field. Especially, we analyse the line splitting of the transverse as well as the longitudinal Zeeman Effect utilizing a Lummer-Gehrcke plate and in the course of that we
Experiment 30 : Normal and anomalous Zeeman effect. I. Background theory. 1. Energy levels of electrons in atoms. 2. Quantum numbers of electron energy levels. 3. Magnetic moment of the electron shell of an atom: a) orbital magnetic moment; b) spin magnetic moment. 4. Atoms in a constant magnetic field: a) Larmor
1 May 2010 Principle. The “Zeeman effect" is the energy shift of atomic states caused by an magnetic field. This shift is due to the coupling of the electron orbital angular momentum to the external mag- netic field. The normal Zeeman effect occurs when there is no spin magnetic moment – states with zero spin are
so we will discuss the Zeeman effect in transitions between singlet states first. Normal Zeeman Effect. For singlet states, the spin is zero and the total angular momentum J is equal to the orbital angular momentum L. When placed in an external magnetic field, the energy of the atom changes because of the energy of its

The Zeeman effect has played an important role in the development of quantum theory. It illustrates the phenomenon of space quantization, which refers to the angular momentum L of the atom assuming only a set of discrete orientations with respect to an external magnetic field B. We recall that an electron in a Bohr circular
2 Dec 2005 The Zeeman Effect was studied using a sample of Neon as the strength of an external magnetic field was varied. The spectrum of the sample was split into vertical dots using a Lummer-Gehrecke plate interferometer. The 626.6nm spectral line was identified both by its characteristic Normal Zeeman Effect.
22 May 2006 In the normal Zeeman effect, the size of the energy splitting from the unperturbed level energy depends only on the magnetic quantum number ml and is, hence, of the same size for all levels in the atom. In the case of the anomalous Zeeman effect, the energy splitting depends on the quantum numbers J, L
