29 October 2020: V.Ivantchenko (emhighenergy-V10-06-02)
- G4hPairProductionModel, G4hBremsstrahlungModel, G4hPairProduction,
G4hBremsstrahlung - added definition of the energy threshold
for creation of a vertex, when energy transfer is above the
threshold (CMS request)
01 September 2020: G.Amadio (emhighenergy-V10-06-01)
- G4hPairProductionModel - inherit ComputeDMicroscopicCrossSection
from G4MuPairProductionModel to avoid code duplication
30 October 2019: I.Semeniouk (emhighenergy-V10-05-06)
- G4GammaConversionToMuons - initialisation of the 5D model cuts size
