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

42 // 18.12.97, V. Grichine (Vladimir.Grichine@cern.ch)
43 // 02.02.00, V.Grichine, new data fEnergy and fVarAngle for double
44 // numerical integration in inherited classes
45 // 03.06.03, V.Ivanchenko fix compilation warnings
46 // 28.07.05, P.Gumplinger add G4ProcessType to constructor
