Dear Makis
FLUKA is not using the EPAX or any other parametrization of fragmentation
cross sections.
The production of individual fragments in a heavy ion collision is
directly predicted by the FLUKA interaction models. Thus, the cross
section follows from the probability that the model produces a certain
fragment and the inelastic interaction cross section. The latter are based
on parametrized predictions by DPMJET-III at high energy and a modified
universal parametrizations by R.Tripathi et al (NASA Technical Report
3621, 1997). Details can be found in
V.Andersen et al, The FLUKA code for space applications: recent
developments, Advances in Space Research 34 (2004) 1302
Therefore, the fragmentation cross sections are FLUKA predictions and
cannot be modified by the user.
Cheers
Stefan
