Question Nuclear de-excitations via gamma rays after nuclear reactions not working? 

Forum: Hadronic Processes
Date: 13 Oct, 2016
From: Brian <Brian>

I am having trouble with a simulation producing high energy gamma rays following a nuclear reaction and I was wondering if anyone could suggest a solution please.

I started with example Hadr3 in order to track all nuclear reactions happening from a 3 MeV deuteron hitting a natural boron target. Published experimental results show the 15.1 MeV state of C-12 is populated and deexcites via a 15.1 MeV gamma ray, but the simulation shows no gamma rays anywhere near that high. Starting from Hadr03, I changed the particle, energy, and target material. Then I commented out the "G4RunManager::GetRunManager()->AbortEvent();" call at the end of stepping action. I would think this would allow all processes to proceed to completion. I tried all the physics lists in the example, but still no 15.1 MeV gamma rays.

Any help would be much appreciated!
