Dear Geant 4 experts,

We are testing the energy loss of electrons in water. We used the TestEm18 example and obtained a very weird result for "low" energy electrons. All the 1 keV electrons we generate experience one interaction after 63.1 microns, and lose all their energy. The stepcut we use is 1 nm, far smaller than this 63 microns length.

Is our set of parameters wrong ? (see attached electron.mac) Do you have any piece of advice ?

Cheers,

Yannick and Isabelle
