Sweet Sweet gamma rays

  1. Nov 9, 2009 #1
    1. The problem statement, all variables and given/known data
    A gamma ray from 198Au incident normally on a thick aluminum slab travels 1.45 cm before it undergoes a Compton scattering. Calculate the range of angles through which the gamma could scatter and still have at least a 10% probability of re-emerging from the incident slab surface without undergoing another interaction.


    2. Relevant equations
    the mass attenuation coefficient for Al at 1.5 cm is .05 MeV
    E[tex]\gamma[/tex]' = Ey / [1 + (E[tex]\gamma[/tex]/E0) (1-cos[tex]\vartheta[/tex])


    3. The attempt at a solution
    IIn the chart of the nuclides do I use one of the gamma energies or is this even the first formula I should be using?
