Zeeman Effect W/ Ccd-camera &

Principle:
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". Usually 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 submitted 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.

Tasks:
1. Using the Fabry-Perot interferometer and a self made telescope the splitting up of the central lines
into different lines is measured in wave numbers as a function of the magnetic flux density.
2. From the results of point 1. a value for Bohr's magneton is evaluated.
3. The light emitted within the direction of the magnetic field is qualitatively investigated.
