Question Difficulty in <5MeV Deuteron, proton interactions 

Forum: Physics List
Date: 27 Feb, 2014
From: Steven <Steven>

Hello all,

I am working on applying Geant4 to the context of fusion research. It has been very difficult to find resources explaining the use of Geant4 for the energy range of, say, <20MeV to <5 MeV with low-energy reactions such as D+D, p+Li, p+C being of interest. (<5 MeV D+D in particular, however).

I was working on this project last summer, but have had to shelve it until very recently. Has anything changed in the way of solutions to this problem from then until now? QGSP_BERT_HP and QGSP_BIC_HP have been the physics lists I've been using for the time being while developing my model-- They are not appropriate for the range I am considering, I know, but are any other stock physics lists better for this use?

I looked up implementing my own physics processes and augmenting the QGSP_BERT_HP and QGSP_BIC_HP lists was extremely difficult. My GEANT4 experience is limited, but I am trying to learn. Are there resources online that instruct how to edit these physics lists/guides which annotate those two lists? Or, even better, do stock solutions exist online for extending GEANT4's functionality down to these lower energy ranges?

Thank you so much. I eagerly await responses and opportunities to move forward on this.
