Hi...
I have to measure the end point energy of a beta minus particle being emitted from a Sr-90 radioactive source. Part of this is plotting a Kurie plot. I am using a pulse height analyser (PHA) to get the beta spectrum (which counts how many beta particles are detected N,on the y-axis and has channel on the x-axis.)
Now I am pretty sure there is an easy way( one that doesn't involve any horrible maths) of doing a Kurie plot by using a variable current and plotting the square of that against N/I^2 (i think).
But as I am using a PHA I don't know how to plot a Kurie plot as there's no change in current that i can read!
Any help as to how i should plot this?
