Alpha Spectroscopy Low Energy Error

  1. Oct 29, 2010 #1
    Hello,

    I've taken a spectrum of a U238 sample, and I keep getting this hill of low energy values. Any ideas as to what could be causing them?

    Sorry about the weird screenshot; it's the only one I had and my friend couldn't see the dots, so i had to go over them in paint.

    What is the scale of the abscissa?

    I would suggest comparing it to a standard alpha spectrum of U-238.
