LB Manganese Work

To observe Mn-54, attempt to find 834 keV (Chan 828.58) with an acceptable decay rate by checking the first and last measurements of Se/Soil (note that the Mn-54 line has a longer half life than Se-75). If the 834 keV line is not visible or decays faster than Se-75 (120 d vs. 312 d for Se-75 and Mn 54 respectively, then reject it as a possibility. I will check both the lowest and the highest concentration as they are upper and lower bounds. Note each of the following histograms are weighted by the mass of the soil.

The total number of counts in the window (after dividing by the run time and mass) is 0.03 for the first measurement and 0.02 for the second measurement
