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 first plot is made when the time is between 0 and 898.6 seconds and this time difference is used for the other cuts as well.
