    "abstract": "A cascade model has been developed to study pion induced multichannel\nreactions (quasielastic, SCX, DCX, absorption and pion production) at pion\nenergies above 0.5 GeV. Special attention has been paid to pion double charge\nexchange. Pion production is a determinant feature in the high energy pion\nnucleus reactions, and the DCX signal not related to pion production is\nsizeable only at forward angles and for high energy outgoing pions. The\ncontribution to DCX of the conventional mechanism, with two quasielastic SCX\nsteps decreases very fast as a function of the energy and reaches very low\nvalues at energies above 0.7 GeV. This opens the opportunity of having sizeable\ncontributions of exotic mechanisms that are negligible at the delta resonance\nenergies.",
