|
// ChangeHistory:
|
|
// 15 June 2007 creation by L. Desorgher. Adapted from G4eBremsstrahlungModel
|
|
// 20-10-2009 Remove all the screening effect that are not considered in the direct models blow 10 GeV. L.Desorgher
|
|
// 4-11-2009 Implement the use of a simple biased differential cross section (C(Z)/Egamma) allowing a rapid computation of adjoint CS
|
|
// and rapid sampling of adjoint secondaries. By this way cross section matrices are not used anymore, avoiding a rather
|
|
// time consuming computation of adjoint brem cross section matrices for each material at initialisation. This mode is switch on/off
|
|
// by selecting SetUseMatrix(false)/ SetUseMatrix(true) in the constructor. L.Desorgher
