HistoryHistory 1998 – FZK (P. Wilson) simple evaporation model; Serber stripping model; experimental data for thick target at 32 MeV analytical formulas used in MCNP source subroutine (McDeli) 1999 – INPE-FZK analytical formulas for deuteron elastic scattering; optical model potentials; intranuclear cascade model; Serber stripping model; experimental data for thick target at 32 MeV ENDF-6 formatted files for deuteron energies up to 50 MeV new source subroutine for MCNP based on NJOY processed files
2001 – FZK revisions of INPE evaluated data based on experimental data for thick targets at 32 and 40 MeV 2004 – FZK revisions of INPE evaluated data (new deuteron elastic scattering data based on phenomenological OMP from 1 to 50 MeV)

Background and goalsBackground and goals
The neutron source for IFMIF is based on d+Li reactions;
Available high energy general purpose d+Li data files fail in description of the experimental data;
General purpose deuteron cross section data files have to cover energies up to 50 MeV;
Data should include particle and photons emission spectra to enable nuclear heating calculations;
Data files should be ENDF-6 formatted for processing with the standard NJOY99 code.
