摘要：

Absolute π±p elastic scattering differential cross sections have been measured at five incident pion energies between 87 and 139 MeV. An active target of scintillator material (CH1.1) was used to detect recoil protons in coincidence with scattered pions. Pions were detected at forward angles between 27 and 98°c.m. where the low-energy recoil protons stop in the target. The cross sections, typically 5-10% lower than phase shift predictions for π+p and 10-20% lower for the π-p cross sections, are consistent with earlier measurements by this group. © 1995 The American Physical Society.
