SAMPLE C
In this sample, it was found that there was a peak at 881 +/- keV
Below the progressive decay of the energy peak can be seen:
The activity of this line was plotted against time since the irradiation. The plot is shown below.
Root gives a half life of 30.2 +/- 4.4 days. After the half life and the energy peak were found, I used rad search and the interactive chart of nuclides to determine that the most likely physics event that occurred would be a single neutron knockout of 85-Rb, with the most intense energy line being 881.6 keV. The half life of 84-Rb is 32.8 days, which falls within one standard deviation of the half life that ROOT gives. There are two other decay peaks at 1016.2 keV and 1897.8 keV. Since these are higher energies, the efficiency of the detector must be taken into accounts when comparing the relative intensities of these lines.
