Re: [fluka-discuss]: neutron cross sections version (ENDF/B-VI?)

... at present 136-Xe cross sections are processed from ENDF/B-7.0
(note 7.0 not 7.1). I did not check if/which are the differences between
7.0 and 7.1: in case it is not a big issue to reprocess from 7.1 If
you give me some more details about what you need, I can be more precise.
BTW for Xenon isotopes we developed in the past an ad-hoc algorithm for
generating correlated capture gammas, I have no idea if it is something
of interest for you.

This uses a highly simplified version of the (n,gamma) cross section for 136Xe, and treats the entire resonance set as an averaged out increase. The cross sections in ENDF/B-VII.1, for example, treat this much more nicely.
