How to increase the probability of a hadronic process

@hungbt1908

I would like to express the hadron process between proton 2MeV and B11 target. I found that the electromagnetic process accounts for all the interactions. I also tried scaling the section up but it didn’t seem to make any difference. Below is my PhysicsList class. Can anyone help me to increase the probability of hadronic processes? Thank you in advance.

Hi, I have the same question about increasing Branch Rate , If something that don’t need Stacking Action can work,please let me know ,thanks.
the link is a question about simulate in only one branch.
