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:

2/14/17 (r5923) 2/15/17 (r5931)
Original Window R5923 FrontNi Foil OGWindow.png R5931 FrontFoil Spec OGWindow.png
Expanded Window R5923 FrontNi Spect ExpWindow.png R5931 FrontFoil Spec ExpWindow.png
Original Background 0.0.6227 +/- 0.1145 0.659037 +/- 0.114807
Expanded Background 0.2953 +/- 0.0645 0.370149 +/- 0.0727176
Signal Background (Take Larger Error) 0.6227 +/- 0.1145 0.659037 +/- 0.114807
Signal in Window (Hz) 203.9 +/- 12.14 226.7 +/- 6.039
Background Subtracted Signal 203.28 +/- 12.14 226.04 +/- 6.04


Below is a table for the rear nickel foil:

2/14/17 (r5924) 2/15/17 (r5932)
Original Window R5924 RearFoil Spec OGWindow.png
Expanded Window R5924 RearFoil Spec ExpWindow.png
Original Background 0.712245 +/- 0.119352
Expanded Background 0.366691 +/- 0.0723771
Signal Background (Take Larger Error) 0.712245 +/- 0.119352
Signal in Window (Hz) 231.6 +/- 7.356
Background Subtracted Signal 230.89 +/- 7.36


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

2/14/17 (r5924) 2/15/17 (r5932)
1.135822511 +/- 0.059600344
