Gamma ray spectroscopy is commonly incorporated in the physics curriculum as part of a modern physics or advanced laboratory course, with Cs-137, Am-241, Co-57, and Na-22 typically used as the gamma-emitters. These isotopes are in excited states, and gamma rays with characteristic energy spectra are emitted when they return to the ground state. The

This is desired for gamma-ray spectroscopy because we are interested in knowing the energies of the various gamma-rays that are emitted by a source. In Figure 3.3, we see what the ideal photopeak created by mono-energetic gamma-rays of a single energy looks like. 3.1.2 Compton Scattering
