So there are really three different reaction classes.
Reaction
- Contains data for a standard (i.e., from an ENDF MF=3 section or a GNDS
reaction
) reaction. UnresolvedReaction
- Contains data for unresolved reactions.
PhotonProduction
- Contains data for photon production reactions (i.e., from an ENDF MF=13 section).
They each contain a variety of parameters read from the evaluation file as well as containing a representation of the cross sections. The representation changes as RECONR progress. It begins as an interpolation table and ends as pairs of energy, cross section values.
