Absolute differential cross sections for {pi}{+-}p elastic scattering at 30 {<=} T{sub {pi}} {<=} 67 MeV

Abstract

Absolute {pi}{+-}p differential cross sections have been measured at incident pion energies of 30.0, 45.0, and 66.8 MeV, using active targets of scintillator plastic (CH{sub 1.1}) to detect recoil protons in coincidence with scattered pions. Statistical uncertainties are typically {+-}3%; systematic uncertainties are {+-}2%. The results are consistent with two earlier measurements by this group employing different experimental techniques at 67 MeV and higher incident pion energies. The {pi}{sup -}p cross sections are in good agreement with currently accepted phase-shift analyses, but the corresponding {pi}{sup +}p predictions are typically 15% higher at large angles than the {pi}{sup +}p data reported here.
