Hello Vitaly,
In your RESNUCLEi card your WHAT(1) is set to 1.0, only spallation
products will be scored. Quoting Fluka's Manual (Resnuclei part) : all
inelastic interactions except those induced by neutrons below the
threshold for multigroup treatment. Is that really what you want ? With
CARBON, it is possible to score all residual nuclei.
Regards.
Sebastien.
