32 // Description: model for inelastic scattering of gammas from nuclei //
33 // including gamma-induced fission. This model is very similar //
34 // to G4LENDCombinedModel except that it does not sample //
35 // elastic or capture reactions since there are no such data //
36 // for gammas in GND. //
