[Tpe] Simulations in 64bit

[Maurizio Ungaro]

The patch02 brought some changes to version 8.1, that might affects these rates, for example:

  o Hadronic Processes:
    ------------------
    + models/coherent_elastic:
      o Introduced NaN check inside G4HadronElastic, G4ChargeExchange, and
        G4UHadronElasticProcess.
      o Removed HP data from G4UHadronElasticProcess (it is set in physics
        lists); added low energy threshold of 20 MeV in G4HadronElastic for
        QElastic. For any particle with kinetic energy below 10 KeV, the
        primary particle is returned unchanged and no scattering is sampled.
        This prevents situations of low-energy neutrons scattering forever,
        and reduces precision in computing scattering for low-energy hadrons.


You can see the full list of changes here:

Notice that this was november 2006 (since then geant4 has been gone through releases 8.2, 8.3, 9.0, 9.1, 9.2 and several patches for each release).


regards,
mauri
