 38 //
 39 // ElectronCapture allows to remove unwanted e- from simulation in 
 40 // order to improve CPU performance. There are two parameters:
 41 //                 
 42 // 1) low energy threshold for e- kinetic energy (default 0)
 43 // 2) the name of G4Region where process is active
 44 // 
 45 //
 46 // If an electron track is killed then energy deposition is added to the step
