What you canlearn about
Discover the splitting of the spectral lines
of atoms within a magnetic field with theZeeman effect.
The Zeeman effect is a classical experiment out of the long
line of Nobel Prize Laureate Experiments offered by PHYWE.
This single system allows study of both the normal as well
as the anomalous Zeeman effect – only a simple filter
exchange is required.
Also the transversal and the longitudinal Zeeman effect
are observable. The combination of these experiments in
only one experimental set-up offers many instructional
advantages.

The Zeeman effect is the splitting of the spectral lines of atoms
within a magnetic field. The simplest is the splitting up of one
spectral line into three components called “normal Zeeman
effect”. Usualy the phenomenon is more complex and the central
line splits into many more components. This is the “anomalous
Zeeman effect”. Both effects can be studied using a cadmium
lamp as a specimen. The cadmium lamp is submittel to different
magnetic flux densities and the splitting of the red cadmium
line (normal Zeeman effect) and that of a green cadmium line
(anomalous Zeeman effect) is investigated using a Fabry-Perot
interferometer. The evaluation of the results leads to a fairly
precise value for Bohr’s magneton.
If observation is transversal to the field (transversal effect), two
lines polarised perpendicularly to the field and one line polarised
parallel to the field are observed, whereas if observation is in
field direction (longitudinal effect), 2 circular polarised lines are
observed.
