Double differential neutron production cross-section for 290 MeV/n carbon ions on carbon. Energy spectra at 6 different laboratory angles, 5° (green), 10° (blue), 20° (cyan), 30° (purple), 40° (gold), 60° (red), and 80° (dark green). The spectra are scaled by a factor of 10. The right plot is with the latest FLUKA improvements, the left one without the PEANUT pre-equilibrium stage addition to rQMD. Symbols: experimental data as measured in [200], revised according to [201].
