Dear Yung-Shun,
I can add to what you exposed just a couple of warnings.
Since you are interested in a correlated analysis on a event by event
basis, you should ask for a "fully analogue" run (WHAT(2)<0.0 in your
GLOBAL card).
Once you know the time of a low energy neutron interaction (ATRACK in
TRACKR, related to the history start) and the involved FLUKA
single-element material (MMTRCK), the point is to check if a capture
took place. Your criterion (no neutron among the NP secondaries in GENSTK)
is correct where only neutron elastic scattering and capture are possible.
But, as soon as more channels are open (with a few MeV neutrons that you
may produce via muon nuclear reactions), it cannot longer be applied,
since unfortunately the available inelastic cross section is not
disentangled into different reactions.
Hope this helps
Greetings
Francesco
