0042 // Class description:
0043 //
0044 // G4ElectronCapture allows to remove unwanted e- from simulation in
0045 // order to improve CPU performance. There are two parameters:
0046 //
0047 // 1) low energy threshold for e- kinetic energy (default 0)
0048 // 2) the name of G4Region where process is active
0049 //
0050 //
0051 // If an electron track is killed then energy deposition is added to the step
