Detailed Description

Set up and launch the neutron inelastic model interaction.

Only neutron-neutron (proton-proton) and neutron-proton channels are tabulated in [10, 320] (MeV) where pion production is not likely. The cross sections below 10 MeV will be calculated on the fly using the Stepanov's function. Tabulated data of cross sections and parameters at the low energy are from G4CascadePPChannel, G4CascadeNPChannel and G4CascadeNNChannel of the Geant4 11.2 release while angular c.d.f data are from G4PP2PPAngDst and G4NP2NPAngDst. Also note that the channel cross sections of nucleon-nucleon are same as their total cross sections in the energy range and the proton-proton channel is same as the neutron-neutron channel based on the charge-independence hypothesis of the nuclear force. See [bertini-1963,hess-1958].
