DD and DT Fusion

Hi dear Geant4 users, how can i simulate these thermonuclear fusion reaction on Geant4. i really need help.
D +T–> n + He4 + 17.60 MeV
D + D → n + He 3 + 3.25 MeV
Thank you for your time.

Here, macros for examples Hadr03 and Hadr07
In PhysicsList.cc, select G4IonPhysicsXS( ).
If you have installed TENDL data set, you can choose instead G4IonPhysicsPHP( )
fusion03.mac.txt (345 Bytes)
fusion07.mac.txt (510 Bytes)

Thank you much. this will help me a lot.
