Dear Fluka experts,
I am simulating neutrons in heavy water and more are escaping than I'd
expect. So I had FLUKA's LOW-NEUT print out the deuterium-neutron cross
sections at room temperature. It gave me a total cross section of 6 barns
when bound in heavy water, which seems lower than the answer that I found
in various articles of 7.6 barns. However I really care about the
absorption cross section. Since this is 10,000 times smaller than the
total cross section, FLUKA rounds the nonabsorption rate to 1.000. So I
learn nothing about the absorption cross section.
Could somebody tell me the neutron absorption cross section on deuterium
(bound, at room temperature) used by FLUKA? Or how to look these cross
sections up with more than 3 significant figures so that I can get the
first nonzero digit of the absorption cross section?
Thank you,
Emilio
