Abstract
The Compton effect is the decrease in energy of a gamma ray photon when it interacts with matter. In this experiment 137-Cs gamma rays, emitted at approximately 0.662 MeV, strike an aluminum rod to produce measurable differences in the recorded energy of scattered gamma rays. The set of procedures is designed to investigate the experimental techniques used to measure the effects of Compton scattering. Using a NaI(T1), photomultiplier tube, ADC/MCA system, and a goniometer - data was collected at various incident angles. Calculated results agree with measured results within an accepted error value of XXXORALCOMPTONXXX.

Error Analysis
For the error analysis, there are two variable associated with an error, θd and θi.
The partial errors for each of the variable are calculated from the formulas
and,
Then the total error is the sum of the two partial derivatives added in quadrature,
The values for δθd and δθi used are half the value of the smallest unit of measure on the device, .05 degrees.
