Description farnea 2003-04-10 05:08:29 CEST

Using the G4PolarizedComptonScattering class, after a few events I obtain
the following message:

G4VParticleChange::SetNumberOfSecondaries() Warning  theListOfSecondaries is not
empty

(the program continues running up to its regular end).
The problem does not occur with the regular Compton scattering class, nor with
the low-energy electromagnetic interactions. I am using Geant4.5.0 with the
latest patch on RedHat 7.3. Eventually, I can send my code to reproduce the
error.

This is one for michel. It seems the semantics of process management has changed
in this respect, and we have to Clear explicitely...

Many greetings,

Hans-Peter.

Since I continued getting the same warning with geant4.8.0, we decided
to have a closer look at the code. Apparently the problem is fixed changing
lines 73-74 from

   if (std::abs(GammaPolarization0.mag() - 1.e0) > 1.e-14)
      G4ComptonScattering52::PostStepDoIt(aTrack,aStep);

to
   if (std::abs(GammaPolarization0.mag() - 1.e0) > 1.e-14)
      return G4ComptonScattering52::PostStepDoIt(aTrack,aStep);

The same obviously will hold for the previous versions!
