Nuclear Spectroscopy

The experiments on alpha, beta and gamma spectroscopy are a continuation of the Öffnet internen Link im gleichen Fensterfundamental course on radioactivity.

The participants measure the discrete energies of alpha particles with a semiconductor detector, their energy loss in air can be quantified and the Rutherford backscattering of alpha particles from a gold foil can be reproduced.

Using beta spectroscopes, the continuous energy spectrum of beta particles is measured. The existence of the neutrinos follows from this result. The velocity of the beta particles is so high that the equations of special relativity have to be considered.

The discrete energies of gamma radiation are measured with scintillation counters. Besides specific radionuclides, XLAB provides different naturally radioactive samples where radioactive isotopes can be identified. Furthermore, the participants can analyze their own samples.

All experiments are introduced with the relevant theoretical background. For an agreement on the desired course content, please contact the Öffnet internen Link im gleichen Fensterteam of the physics department.
