FLUKA does not consider polarization in inelastic AA collisions. Moreover,
inelastic deuteron interactions below 100MeV/n cannot be simulated with

More precisely, STUPRF is called every time before hadrons, muons,
neutrinos, low-energy neutrons, heavy ions or optical photons are copied
into the stack. It is sometimes used to carry over additional properties
are information from the parent to the daughter particles.

Information regarding initial and final states of interactions are
available in user routine mgdraw (activated with the card USERDUMP) under
entry USDRAW. Information on the parent particle can be read from common
TRACKR, while those of the final state particles are in commons GENSTK.

In theory I would think so, but you have to ensure energy-momentum
conservation between initial and final state of the reaction, including
heavy recoils etc. Thus, I am not sure this is really recommended...
