 37 // Class description:
 38 //
 39 // G4LowECapture allows to remove unwanted particles from simulation in 
 40 // order to improve CPU performance. There are two parameters:
 41 //                 
 42 // 1) low energy threshold for kinetic energy (default 0)
 43 // 2) the vector of names of G4Region where process is active
 44 // 
 45 //
 46 // If a track is killed then energy deposition is added to the step 
 47 //
