Neutron knockout on Se-82

While looking to see if certain lines are indeed selenium within the spectrum, it is worth noting that there are 2 states for Se-81. There is a metastable state with a 57 minute half life and a gamma emission of 103 keV. First I will attempt to show that this metastable state can indeed be seen in the spectrum.

Below is an overlay of 5 plots with different cuts in time.

The half life was calculated using the program /data/IAC/Se/Feb2017Run/LB_WeightedFit.C
