I want to change the direction of an e- comming from a Beta-decay. The plan is to redefine the particles momentum after the first step an to put it back where ik came from. This all in steppingaction.
I tried: theStep->GetPost(or Pre)StepPoint()->SetMomentumDirection(G4ThreeVector(1,0,0)); theStep->GetPost(or Pre)StepPoint()->SetPosition(initialPosition); This is just ignored.
I also tried theStep->GetTrack()->SetMomentumDirection(G4ThreeVector(1,0,0)); theStep->GetTrack()->SetPosition(initialPosition); Then the position and momentum of the particle changes, but i get warnings that the information is not reliable anymore.
Am i doing this in the wrong way or do is just have to add something else?
