The differential cross section of the reaction π~ +d~*p+ тт~ -\-n (at a c.m.s. proton emission angle close to 0°) was measured in the momentum interval from 1.25 to 2.64 GeV/c. The measured cross sections turned out to be equal, within the limits of statistical accuracy, to the cross section of elastic π~ρ backscattering at the investigated energies. The result confirms the important role played in this process by the interaction in the final state.
