Introduction to GEANT4

You can use the class <span style="color:#ff0000"> G4VUserPhysicsList </span> if you want simple physics lists. <span style="color:#ff0000"> G4VUserPhysicsList </span> has three methods:

<u> Simple example of <span style="color:#ff0000"> MyPhysicsList </span> derived from <span style="color:#ff0000"> G4VUserPhysicsList </span> </u>:  

In method ConstructProcess() you define your physics processes:

In methods ConstructEM() and ConstructGeneral() you assign the physics processes to the corresponding particles:
