36 // Class description:
37 //
38 // G4ElectronCapture allows to remove unwanted e- from simulation in
39 // order to improve CPU performance. There are two parameters:
40 //
41 // 1) low energy threshold for e- kinetic energy (default 0)
42 // 2) the name of G4Region where process is active
43 //
44 //
45 // If an electron track is killed then energy deposition is added to the step
46 //
47 // This example is provided by the Geant4-DNA collaboration
48 // Any report or published results obtained using the Geant4-DNA software
49 // and the DNA geometry given in the Geom_DNA example
