Question Angular distribution from Hadronic process 

Forum: Hadronic Processes
Date: 12 Jul, 2016
From: Pierre Morfouace <Pierre Morfouace>

Dear all,

I simulate 60 MeV proton into 1 mm of natural tin and I look at the angular distribution using different physics list.

First of all when I use only a physics list with the multiple scattering I have the expected behavior with a gaussians a low theta and a Rutherford tail for larger theta. However I want to use hadronic processes, so in a second step I loaded the HadronicElastic process as well as the Binary cascade using the Tripathi and Shen cross section parametrization and I was expecting a drop of the number of counts after the grazing angle while the behavior is similar to the multiple scattering one up to 30 degrees and the counts become higher at larger angle (I attached the picture here: red for only MSC and blue for MSC+hadronic process).

Should I load another specific physics list or cross section to see the drop in the number of counts around the grazing angle?

I am doing this test because I wand to estimate the efficiency loss of detecting the full energy due to nuclear reaction in a material.

Thank you for your help.

Regards Pierre
