// Description: model of muon nuclear interaction in which a gamma from
//              the virtual photon spectrum interacts in the nucleus as
//              a real gamma at low energies and as a pi0 at high energies.
//              Kokoulin's muon cross section and equivalent gamma spectrum
//              are used.
