Below are the Half life plots and hte point by point ratio plots for the mixture and the pure selenium sample. Note the error in the mixture.

Nickel Foil Information

For the nickel I have been using counting statistics ([math] \sqrt N[/math]) to find the error in the signal. This is due to the fact that I can pin down the half life within uncertainty using this type of error.

Below is a table for the front outer nickel foil that was used in the sample.

Flux Simulations

The purpose of the flux simulations is to find if the factor that makes my ratios different than Segebade's. Below is the flux through the nickel foil.
