Differential cross sections for π + p elastic scattering were measured for seven incident energies from 65 to 140 MeV at laboratory scattering angles between 93° and 165°. The results are compared with previous results of Bertin et al. and the phase-shift analysis of Arndt and Roper. Agreement between the phase-shift analysis and the data is good.

The differential cross section for scattering of pions on deuterons was measured at LAMPF at laboratory momenta of 343, 441, 539, and 637 MeVc, using an E−ΔE method to identify the recoil deuterons. Angles ranged from 40° to 160° in the center of mass system. The momentum resolution was σ=±3.5% and the angular resolution was ± 1.70° in the laboratory system. The experimental method is discussed, and results are presented and compared with other experimental data as well as with various theoretical calculations.
