39 // Class description:
40 //
41 // G4ElectronCapture allows to remove unwanted e- from simulation in
42 // order to improve CPU performance. There are two parameters:
43 //
44 // 1) low energy threshold for e- kinetic energy (default 0)
45 // 2) the name of G4Region where process is active
46 //
47 //
48 // If an electron track is killed then energy deposition is added to the step
