Question High Energy Deposit in Few Cases 

Forum: Hadronic Processes
Date: 09 Jan, 2017
From: <jeonyboy@gmail.com>

Hello, so I've been running 45 MeV proton on 10 nm of silicon using simulation similar to hadr06. Most deposit energy around 2.5E-05 MeV (2.5 eV) but there are very few cases where it deposits more than 0.08 MeV (shown in attached file). The stopping power calculation also result in 2.5E-05 MeV (2.5 eV).

I was under the impression that this was due to nuclear reaction and secondary particle energy deposition but the simulation doesn't show any List of Generated Particles. Am I correct in thinking then that these few high energy deposit cases are due to ion to ion hit such as proton atom hitting the silicon atom?

Also, this is a long shot but I am simulation 5 MeV Alpha in same 10 nm of silicon but it doesn't seem able to deposit more energy than 0.08 MeV unlike the proton case in above. This is peculiar to me because I have some test data that says 5 MeV alpha did deposit more than 0.08 MeV in silicon.

Any help on either or both will be greatly appreciated! Thank you.
