I run a simulation where I have only NeuLAND in the setup. I shoot 1 GeV neutrons
onto NeuLAND (14 m distance, 4.5 degrees angular spread, box generator). When I
run this simulation under TGeant4, I only find a few different tracks is the MCTrack-branch
of the output-file. When I however run the same simulation under TGeant3, The MCTrack
branch is much larger. In further analysis, this results in that Geant4 gives only
40% detection efficiency for NeuLAND, while Geant3 given 99%. Does anyone know
why my Geant4 results are wrong?

Christiaan.

PS: The histogram included is the size of the MCTrack branch under Geant4.
