Upon further investigation the problem I am having is not with ParaFission.
When I look at the results of the LHadron capture it is at that point that
the simulation is producing U-239 when it should be making U-236.
When I attempted to use Pu-239 as my fissile material I received the
the following error:

 *** Break *** segmentation violation
 Generating stack trace...
 0x035c89b1 in G4NeutronHPCaptureData::GetCrossSection(G4DynamicParticle
 const*, G4Element const*, double) + 0x379 from /opt/geant4/pro/lib/
I then attempted to use the G4LCapture model rather than the 
G4NeutronHPCapture model and I received the following error:

In src/, line 151:
===> G4Nucleus::SetParameters called with non-physical parameters
Unrecoverable error for:
 - Particle energy[GeV] = 2.5e-11
 - Material = Pu239
 - Particle type = neutron
*** G4Exception : 007
      issued by : G4HadronicProcess
GeneralPostStepDoIt failed on element selection.
*** Fatal Exception *** core dump ***
*** G4Exception: Aborting execution ***

Could there be a problem with the way Geant is constructing the
materials?  Help if you can.
