I am a bit confused now. In the docs I have read that a new feature of G4 is the unique treatment of cuts as _range cuts_, which are converted to energy in each material.
As suggested in this article, however, it is not enough to define range cuts for different particles, one also has to set an energy cut, additinally. As Leif pointed out, by changing the range cut for a particle one can not go below 0.99keV energy threshold, and this can only be done by changing the _energy_ cut in ProductionCutsTable (by VI).
My question is: which value is than used as the real production threshold? The one calculated from the range-cut, or the energy-cut defined in the ProductionCutsTable? Could someone point me to right point in the G4 documentation about this topic?
