Re: FLUKA: FLUSCW

[Stefan Roesler <Stefan.Roesler@cern.ch>]

Hi Laurent,

The argument list of fluscw is explained in the header of that file, e.g.

*          Pla = particle momentum (if > 0), or kinetic energy (if <0 )*

The energy limits for the low-energy neutron groups can be found in the
manual. Please find them below as fortran data-statements.
