Hi ROOT (and VMC) experts,
I have a working VMC application. It works fine when I use a beam of protons: I can see delta rays, energy losses and hadronic interactions (pion production) with all the three MCs.
If I define ions
gMC->DefineIon(“C12” , 6,12, 6, 78.01.e-09,12.000AMU);
and I try to use them as a beam ( fStack->PushTrack(toBeDone, -1, 1000060120, …) ),
as a result I could see the ion delta rays production and energy losses (propto Z2),
but I couldn’t be able to see any hadronic fragmentation.
This happens with all the three MCs.
This are my settings:
What is the possible source of this problem?
