Pi- p backward elastic scattering between 1.28 and 3.0 gev/c

Ott, R.J. ; Trischuk, J. ; Va'vra, J. ; et al.

Phys.Lett.B 42 (1972) 133-135, 1972.

Inspire Record 85045 DOI 10.17182/hepdata.76247

The differential cross-section for π - -p elastic scattering over the angular range 125° to 178° center of mass has been measured between 1.28 and 3.0 GeV/ c . Considerable structure is found and is discussed in terms of direct channel resonances.

Pi+- and pi0 production by polarized photons in the resonance region

Alspector, J. ; Fox, D. ; Luckey, David ; et al.

Phys.Rev.Lett. 28 (1972) 1403-1406, 1972.

Inspire Record 75484 DOI 10.17182/hepdata.21872

We have measured the cross sections at 90° c.m. for π± and π0 photoproduction with polarized photons. The photon energies ranged from 0.8 to 2.2 GeV. We compare the resonant "bumps" in the cross section with theoretical models. The measured asymmetry agrees with a quark-model calculation though the predicted cross sections are low.

Pi- p elastic scattering near 180 degrees between 600 and 1280 mev/c

Crabb, D.G. ; Keller, R. ; O' Fallon, J.R. ; et al.

Phys.Rev.Lett. 27 (1971) 216-219, 1971.

Inspire Record 68952 DOI 10.17182/hepdata.21460

The differential cross sections for π−p elastic scattering over the angular range 155° to 177° in the center of mass have been measured at 33 incident-pion momenta in the range 600 to 1280 MeV/c. Angular distributions are presented. The extrapolated differential cross sections at 180° show considerable structure, in particular a dip near 1150 MeV/c. In general the near-180° cross sections do not agree with existing phase shift solutions above 1000 MeV/c

Differential Cross Sections in Eta Photoproduction from 0.8 to 1.45 GeV

Bloom, E.D. ; Heusch, C.A. ; Prescott, C.Y. ; et al.

Phys.Rev.Lett. 21 (1968) 1100-1103, 1968.

Inspire Record 54471 DOI 10.17182/hepdata.21721

The cross section for the process γp→pη was studied from 0.8- to 1.45-GeV incident photon energy at center-of-mass angles from 50 to 90°. The data cover a range of energies well beyond previous measurements. The results will aid in the study of I=12 nucleon isobars.
