Hello,
This topic has been already discussed.
You could find helpful hints following these links :

Since FLUKA2008.3 release, there is a new neutron cross section library=20
with 260 energy groups which is now the default one (the one with 72=20
groups is still available), so it would be wise to follow Alfredo's=20
advice (second link) and not bin into those 260 energy bins but simply=20
declare in source.f file the bins of your own data, i.e. your Cf or AmBe=20
spectrum.
Hope it helps.
Regards.
Sebastien.
