first of all FLUKA simulates, through the PEANUT package, all
the few-GeV pion-nucleus reactions, that you want to study:
- Channels for momentum of pion(+)=3D2.34 GeV/c
pion(+) + Xe -> pion(0) +A'
pion(+) + Xe -> proton + pion(0) +A'
pion(+) + Xe -> proton + A'
- Channels for momentum of pion(-) =3D 3.5 GeV/c
pion(-) + Xe -> pion(0)+ A'
pion(-) + Xe -> proton + pion(0) +A'
pion(-) + Xe -> proton + A'
You cannot, however, simulate single nucleus interactions with FLUKA.
A good solution to this first problem could be to approximate your
reaction by using a thin Xenon target: in this way you could get
a lot of informations about your final states.
You have, however, a second problem: you cannot get all information
you need about the initial state (you cannot get impact
parameters, etc...), that means that you cannot extract a random impact
parameter as you want to do.
One comment more. In principle the PEANUT event generator can be called
in the source.f user routine, but it would violate the point 3. of the
FLUKA user licence: following this point, you cannot "....modify any
of the functions of FLUKA, or extract specific isolated results from any
of the individual internal physics models embedded within FLUKA".
Hope it could help somehow,
