=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.

Latest revision as of 01:19, 29 March 2018

Below is the information for the target

Front Outer Nickel Foil: 3.4274g

Outer Se: 0.0914g

Soil: 10.240g

Inner Front Foil: 1.8672g

Inner Rear Foil: 1.7220g

Inner Se: 0.0954g

Rear Outer Foil: 3.4887g

Below is a table with the data that is to be analyzed for 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.
