Dear Fluka users,
I would like to extract cross section data from Fluka simulations.
I am quite comfortable with fluka routines source.f, mgdraw.f...
Is someone have already do this kind of study?
I am really interested by this challenge because it seems that this is no easy way to access to cross section in FLUKA.
If someone can help me...
Thanks
Best regards

Hi
I have to specify better what I wrote in my previous e-mail, I was
misleading.
Fluka uses a parametrization for the TOTAL p-nucleus cross section. The
specific reaction channels are NOT derived from
databases/fits/parametrizations: they are calculated online from
microscopic models of the reaction. So, there is no easy way to access
cross sections for single reaction channels.
Regards
Paola
