0040 //
0041 // G4ElectronCapture allows to remove unwanted e- from simulation in
0042 // order to improve CPU performance. There are two parameters:
0043 //
0044 // 1) low energy threshold for e- kinetic energy (default 0)
0045 // 2) the name of G4Region where process is active
0046 //
0047 //
0048 // If an electron track is killed then energy deposition is added to the step
