Determination of large-angle cross-sections for π-+p → π-+Δ+ at 5 GeV/c

We have measured the differential cross-section for the process π-+p → π- + Δ+ in thet interval (1.74/3.5) (GeV/c)2 at 5 GeV/c. At the largestt-values, the cross-sections have the same magnitude as the π-p elastic cross-sections.
