As a first attempt at extracting the half life of the 103 keV line, the following procedure was followed:
 
−
 
−
1)Fix a window around the line of interest.
 
−
 
−
2)Do a pol0 fit to estimate the background.
 
−
 
−
3)Integrate the output of the pol0 fit within the window region.
 
−
 
−
4)Use SetOptStat commands to get the integral over the entire window.
 
−
 
−
5)Subtract the background and divide by the run time to get the activity.

−
Below is an example of this process.

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.
