Photon Energy deposition in a pure Ge crystal

Determine the deposition of photons ranging in energy from 10 eV to 3 MeV in a pure Germanium crystal assuming an infinite block.

Attenuation coefficient about 1/5.323 cm = 0.19 cm or about 2 mm to maybe 2 cm?

Create file containing Photon Energy, ProcessID, step #, Energy Lost, Position for each step a photon takes through the Germanium crystal.
