// Class description:
|

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