Multiple scattering laws for evaporation spectra #5

Closed paulromano closed 12 years ago

paulromano commented 13 years ago

Some reactions specify multiple scattering laws. This is mainly used for (n,xn) reactions. In such reactions, the emission of each neutron corresponds to a different excitation energy of the compound nucleus and thus they have different observed energy spectra.

This could be done by having a pointer at the end of the AceEnergyDist pointing to another AceEnergyDist (as many times as necessary).

This capability was implemented as of commit 58a5f8. F-19 has multiple energy distributions for (n,2n), so I built a model for LEU-SOL-THERM-001 which contains that nuclide and compared to MCNP5. keff agreed within ~0.05%.
