Thank you very much for your help to a beginner.
Now I could have a couple of runs completed.
I encounter difficulty interpreting my results.

Without normalization, could I interpret the result like single proton
contribute around 0.0008 neutron production within bin 0-18deg,
The population of neutron in energy bin 0-3.5MeV is less than bin
0-1.5MeV ,the angular distribution deviates compared with ICRU.
Did I still make obvious mistakes?

My Best Regards
