The total cross section and the differential cross sections of the reactions π + d →π + d (elastic scattering) →π + pn (inelastic scattering) →π 0 pp (charge exchange scattering) →γ pp (radiative absorption) → pp , (non-radiative absorption) have been measured using 85 000 pictures of 290 MeV/ c positive pions in the 38 cm Princeton-Pennsylvania bubble chamber. The elastic, inelastic and charge exchange scattering data are more complete than any previous data in this energy range.
FOUND BY EXTRAPOLATION OF PARTIAL CROSS SECTION TO ZERO SOLID ANGLE.
TOTAL NUMBER EVENTS= 3400.
