LB Feb Nickel Consistency Check

This analysis was done on Inv # 170010 which was irradiated in February 2017 with a rotating sample holder. This was a 50% mix of Se and Soil. The mass of the front nickel foil was 0.27 grams and the mass of the rear nickel foil was 0.25 grams. The histograms made were weighted by the time of the run and the mass of the nickel foil.

Below is a table for the front nickel foil:

Since the efficiency is unknown I will plot the ratio of the activities so the efficiency cancels out. Below is a table of rations that will be entered into a .dat File
