MEASUREMENT OF LOW-ENERGY ELASTIC PI+- P DIFFERENTIAL CROSS-SECTIONS

Frank, J.S. ; Browman, A.A. ; Gram, P.A.M. ; et al.

Phys.Rev.D 28 (1983) 1569-1585, 1983.

We have measured differential cross sections for both π+p and π−p elastic scattering at incident-pion kinetic energies of 30, 50, 70, and 90 MeV in the center-of-mass angular range between 50° and 150°. The experiment detected pions scattered from a liquid-hydrogen target with multiwire proportional chambers and scintillation-counter range telescopes. The relative accuracy of each angular distribution is better than 5%, while the absolute cross sections have uncertainties of 4% to 25%. Our results for the absolute cross section for π+p scattering at 30 and 90 MeV are inconsistent with previous measurements. Our π−p measurements comprise the first extensive set of precision differential cross sections below 90 MeV.

The Slope of Forward Elastic pi+ p Scattering from 4.4-GeV/c to 6.0-GeV/c

Rey, C.A. ; Poirier, J.A. ; Lennox, Arlene J. ; et al.

Phys.Rev.D 15 (1977) 59, 1977.

Inspire Record 109729 DOI 10.17182/hepdata.24605

Angular distributions for π+p→π+p were measured for 13 incident-pion momenta from 4.4 to 6.0 GeV/c and for −t less than ∼0.1 (GeV/c)2. This experiment was performed at the Zero Gradient Synchrotron of Argonne National Laboratory, where a focusing magnetic spectrometer and a scintillation-counter hodoscope were used. In fitting the angular distributions the strong-interaction contribution was parameterized by an exponential form exp(bt); the Coulomb interference was also included. The resulting values of the slope parameter for |t|<∼0.1 (GeV/c)2 are presented for each incident beam momentum.
