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.
