Re: FLUKA: Cross section output

[Laurent APHECETCHE <aphecetc@in2p3.fr>]

Hi Alberto,

Thank you very much for your answer.
Indeed, if I understand correctly your mail, it seems impossible from
this output to infer the (total) capture xsec itself, right ?

Actually, I would have another question. Is it possible to investigate
the influence of input neutron libraries, e.g. is it possible to produce
a new set of such input libraries (for selected elements, I think first
of 209Bi in my case) ? How much work would it be for me (is it
feasible/desirable at all ?)

Best regards,
