The specific reason for our need of equation 12 will be shown in the following sections. A primary focus of our experiment is to understand the differential cross section. To do this we will take a look at the classical Thomson formula as well as the quantum Klein-Nishina differential cross section. The derivation of these two equations are beyond the scope of this lab report. If one was curious enough to see the derivations, please consider the citations at the end of the report.
    Consider the classical Thomson formula below.
