Absolute [pi][sup [plus minus]][ital 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 ([ital CH][sub 1.1]) was used to detect recoil protons in coincidence with scattered pions. Pions were detected at forward angles between 27 and 98[degree][sub c.m.] where the low-energy recoil protons stop in the target. The cross sections, typically 5--10% lower than phase shift predictions for [pi][sup +][ital p] and 10--20% lower for the [pi][sup [minus]][ital p] cross sections, are consistent with earlier measurements by this group.
