FLUKA: neutron cs weighting function
Hi,
Does enybody know what exact weighting function has been used to produce
the Fluka neutrons library neuxsc_72.bin ?
In original article of Cuccoli,Ferrari,Panini (JEF-DOC-340) there is
written only a general shape (Maxwellian+1/E+fission+1/E+fussion) -
an adoption from the VITAMIN-J library.
But what are the energy cutpoints, what are the spectra parameters ?
For instance, the energy cutpoint between Maxwellian and 1/E:
1. In VITAMIN-J description (JEF rep.10) one can find "see VITAMIN-E"
2. In VITAMIN-E report (DLC 113, page 3) there is writen "...it is
temperature dependent" but afterwards "...is fixed at 0.414 eV
INDEPENDENT of temperature (the original 5 kT guideline was only
nominal)"
3. From my own calculations and comparisons with FLUKA data it is
rather 5 kT than 0.414 eV
4. D.Cullen in his widespread ENDF PREPRO programs uses here 4 kT
What we really have in our FLUKA neuxsc_72.bin library ?
d.d.
