π+–p elastic scattering at 47.9 MeV

The differential cross section for π+–p elastic scattering at 47.9 MeV has been measured in the angular range from 30 to 170° in the laboratory system. The three phase shifts extracted from these data, δS3 = −4.7 ± 0.5°, δP31 = −0.53 ± 0.14°, and δP33 = 5.1 ± 0.3°, are consistent with phase shifts obtained at other energies.
