Interference effects in inclusive charge-exchange p+p→n+X and n+p→p+X reactions at intermediate energies

The formalism of Feynman diagrams to describe charge-exchange reactions p+p→n+X and n+p→p+X on a free proton target taking into account spectator and decay modes in the π+ρ+g'-model have used. It is shown that the interference between these modes depends on the set of vertex function parameters used. It is also shown that the constructive interference of the Δ+ and Δ0-isobars is important. 22 refs.; 10 figs
