// G4TransitionRadiation -- header file
|
|
//
|
|
// Class for description of transition radiation generated
|
|
// by charged particle crossed interface between material 1
|
|
// and material 2 (1 -> 2). Transition radiation could be of kind:
|
|
// - optical back
|
|
// - optical forward
|
|
// - X-ray forward (for relativistic case Tkin/mass >= 10^2)
