Question Implement channel cross sections 

Forum: Hadronic Processes
Date: 30 Jan, 2012
From: Neoh <Neoh>

Hi all,

I'm trying to study the feasibility to implement more than channel cross sections for a projectile energy less than 50 MeV. I saw the following post:

http://hypernews.slac.stanford.edu/HyperNews/geant4/get/hadronprocess/489/1/1/1/1/1/1.html

and I have one question, maybe I misunderstand something, and I'd be grateful if someone can help me out.

Let's say I have two channels of reaction called channel A and channel B, and cross section of A is always smaller than channel B. In real experiment we would have secondaries resulted from both channel reactions, only channel A produce less than B because of smaller cross section. From the Geant4 point of view however, since all hadronic processes are inherited from G4VDiscreteProcess, and the interaction length of reaction B is always shorter than A, so reaction channel A will always be ignored, as a result only reaction B is simulated.

Is there something wrong with my understanding?
