Question determining which atomic nucleus a secondary came from 

Forum: Hadronic Processes
Date: 13 Oct, 2010

Dear all,

I am trying to find out which atom of a compound material produced certain secondaries. specifically, I am interested in reactions between a proton beam and soft tissue, and would like to know which element inside the soft tissue created either positrons or gammas.

I had originally posted this on the Event and Track management forum, but have been referred to here. My original post is below, but for the full story please follow the link.

as you will see in the link, Peter has helped me get back to the name of the process. But I am not sure how to get to which atom was involved in the reaction.

Any suggestions and comments are very much appreciated.

thanks ,


Dear all,

I am wondering how to extract from geant4 which nuclear reaction has caused positrons to be created. I am firing a proton beam into soft tissue and in some instances positrons are created. But for each positron I would like to know which atom of the complex material compound was responsible for the positron being emitted i.e. was it carbon, nitrogen, oxygen (etc) .

Unfortunately I dont really know where to start with this.

Is anyone kind enough to help?

Thanks in advance,
