Dear Ana
maybe I'm missing the context, but I do not think that the procedure you
mention is the correct one to simulate the Fano theorem.
The Fano theorem is usually applied to the study of small cavities at low
density ( like TEPC detectors) for dosimetry. The smallness ensures that
the particle fluence is not perturbed by the cavity. To test this, the
"source" should be external, like a broad beam irradiation. The beam
should not be relativistic (density effects are present at relativistic
energies), The transport thresholds should be set at the same energy in
all the volumes, and low enough when compared to the detector dimensions
and density. The CORRFACT card shall NOT be used, non-relativistic cross
sections are already density independent.
Ciao
