Gamma-ray production matrices for cosmic-ray protons and helium

Here you can download gamma-ray production matrices for cosmic-rays (protons and helium) up to an incident total energy 10^8 GeV, using a parametric model for E< 10 GeV and the high-energy event generator DPMJET-III for E > 10 GeV.

It is strongly recommended to read the manual prior to using the matrices.

You can download the manual as pdf file or as ps file.

Note: We request that you cite the following article, if you use the data/documents from this website.
