USRYIELD results

Scoring
1

Dear FLUKA experts,
I am using the USRYIELD card to score the neutron double differential yields in the unit of (#/GeV/sr/primary) in a 16 MeV photon-induced reaction.

In a case of a thick target, is the neutron attenuation considered by FLUKA using this scoring card?

Thank you.

Yes, if you score on a region boundary (produced neutrons are transported through the target up to the boundary).
No, if you score neutrons EMERGING from nuclear reactions.
