Homework Help: Solid plastic scintillator, Pilot B

  1. Apr 8, 2007 #1
    1. The problem statement, all variables and given/known data

    Calculate the energy loss [tex]\Delta[/tex]T of protons, deuterons and [tex]\alpha[/tex]'s between 10 and 200 MeV in passing through a 2-mm thickness of solid plastic scintillator (the name of the plastic seems to be Pilot B).

    2. Relevant equations

    The stopping power equation, which is too long for me to write here, though.

    3. The attempt at a solution

    [tex]\Delta[/tex]T should be (dT/dx)*thickness of scintillator. My main problem, however, is with the scintillator. I have been given it's density (1,03 g/cm^3), but the stopping power requires me to have it's different Z and A values as well as its I values. The obvious problem is to know what the constituents of this plastic are, and how many of each sort of them there are in a "plastic molecule" of this kind. I'm lost!
