Hello everyone,
-
I’m simulating a nuclear physic experiment used a 1.5 MeV proton bombed a target (B10 + Al27). There are 6 detectors placed around target to detect particles emitted from proton interaction with the target. I used each detector to record energy deposition of each case particle (proton, alpha, Be7, B11, B10, gamma, and other particle).
-
I constructed my PhysicsList like “examples\extended\hadronic\Hadr01” example and run my simulation for 25 PhysicsList cases:

- The results:I exported results to root files. But I just got some pretty bad results. I found that only with the QBBC library are the probes able to detect alpha. The table below summarizes my results.

Which physics library should I use to simulate this problem? The above results are all run with 1E9 events. The detection results are still too low.
Should I use UserPhysicsList or not? And how to build it. I’m not someone who understands physics very deeply. Can someone help me?
Thank you in advance.
