Sorry for posting in old thread!!! I have a confusion related to this. Incident particles are moving in Z-direction. I have to score particles in cone whose half angle is 7.5 deg and having azimuth symmetry. In order to do this, G4double Z = pd->GetPDGCharge()/eplus; G4double dirY = track->GetMomentumDirection().y(); G4double dirZ = track->GetMomentumDirection().z(); G4double theta = std::atan(dirY/dirZ); G4double Theta2 = track->GetMomentumDirection().theta(); if(Z>0) if(-7.5<= theta/deg && theta/deg <= 7.5) histo->fill(2,Z,1.0);
I am not sure that am I doing right to calculate the (secondary) particles emitting from a desired cone?
I would also like to know what is the difference between theta and Theta2? And how track->GetMomentumDirection().phi() is different from this? From where can I get the complete documentation related to G4ThreeVector so that I can complete understand about all these.
With kind regards, Summit.
