We investigated the backward elastic π~ρ scattering at primary momenta 24.7 and 37.8 GeV/c using a magnetic spectrometer with hybrid spark chambers. Experimental results are presented on the dependence of the differential cross section άσ/du on the squared momentum transfer w, and also on the energy dependence of άσ/du at и = 0.
