40 | // 15 June 2007 creation by L. Desorgher. Adapted from G4eBremsstrahlungModel |
---|
41 | // 20-10-2009 Remove all the screening effect that are not considered in the direct models blow 10 GeV. L.Desorgher |
---|
42 | // 4-11-2009 Implement the use of a simple biased differential cross section (C(Z)/Egamma) allowing a rapid computation of adjoint CS |
---|
43 | // and rapid sampling of adjoint secondaries. By this way cross section matrices are not used anymore, avoiding a rather |
---|
44 | // time consuming computation of adjoint brem cross section matrices for each material at initialisation. This mode is switch on/off |
---|
45 | // by selecting SetUseMatrix(false)/ SetUseMatrix(true) in the constructor. L.Desorgher |
