Hi! I´m also having problem with muon captured. I produce muon minus in a liquid scintillator detector, (Carbon and Hydrogen). The muons make ionization processes and once they are at rest they are captured by carbon (Globaltime ~3ns).
Looking at the bibliography I found that in carbon the muons (most of them) should decay before they make the reaction:
12C + mu -> 12B + neutrino (*)
because their lifetime is ~2 microseconds and the nuclear absorption (*) happens at ~20 miliseconds.
In my simulation it works, usually the muon decays before it makes the nuclear absorption. I see electrons and gammas from the electromagnetic cascade (produced at ~3- 4 ns Globaltime) and then the two neutrinos and the electron from the decay. The neutrinos are produced at the time expected, ~ 2.2 microseconds (~2200 ns globaltime) after the production of the muon. BUT the electron from the decay is produced at GLOBALTIME ~3ns!!!
This produced of course a wrong signal in my detector because the optical photons that this electron produced arrive at the wrong time. I was looking at the code where that is implemented:
and I can not found where is the problem.
Maybe someone have an idea? Thank you!
