JHU Advanced Physics Lab: Nuclear spectroscopy
There is a good manual available for this experiment, but it is available
only by request and next to the apparatus.
Make request to the instructor to get a copy.
Technical description is available here .
First you have to perform energy calibration (experiment 1).
Then measure spectra for common sources and identify content of the
unknown source (experiment 2). Measure energy resolution as a function
of energy using the above spectra (experiment 3).
Study Compton scattering (including back-scattering)
and search for annihilation and escape peaks
(experiments 4 and 5). The last search may require several hours
to collect data.
Prior notes on this experiment may be helpful and can be found
here .
In this experiment you will perform an experiment which almost 100 years ago
provided support for the first quantum models of the atom by Bohr.
