Pi0 and pi+ Production with Polarized Photons in the Energy Range 1-GeV - 2-GeV

Abrahamian, L.O. ; Avakian, R.O. ; Aganyants, Aleksandr O. ; et al.

Phys.Lett.B 48 (1974) 463-466, 1974.

Inspire Record 90760 DOI 10.17182/hepdata.43798

The asymmetry of π o and π + photoproduction from hydrogen has been measured. The π o -mesons were detected at 130° cms with E γ ranged from 0.9 to 1.65 GeV, and the π + -mesons at 40° cms with E γ ranged from 0.9 to 1.2 GeV. The results agree with model predictions of single pion photoproduction in the resonance region using fixed- t dispersion relations.

PRODUCTION OF F-prime (1520) IN 8.25-GEV/C K- P INTERACTIONS

The BIRMINGHAM-CERN-GLASGOW-MICHIGAN STATE-PARIS collaboration Al- Harran, S. ; Baubillier, M. ; Bloodworth, I.J. ; et al.

Nucl.Phys.B 191 (1981) 26-38, 1981.

Inspire Record 172450 DOI 10.17182/hepdata.34233

We present results for the hypercharge exchange reaction K − p→f' λ from a high statistics experiment at 8.25 GeV/ c using the CERN 2m HBC. The total and differential cross sections have been measured; the polarisation of the Λ hyperon and the f' density matrix elements have been calculated as functions of momentum transfer. We also present detailed information on the relative strength of the natural and unnatural parity exchange contributions to the production mechanism.

Differential Cross-sections and Analyzing Powers for Small Angles $N P$ Elastic Scattering Between 376-{MeV} and 1135-{MeV}

Silverman, B.H. ; Lugol, J.C. ; Saudinos, J. ; et al.

Nucl.Phys.A 499 (1989) 763-788, 1989.

Inspire Record 264337 DOI 10.17182/hepdata.36902

We have measured absolute differential cross sections and analyzing powers for neutron-proton elastic scattering for momentum transfer 0.01 < | t |< 0.08 (GeV/ c ) 2 at several energies between 378 and 1135 MeV. The ionization chamber IKAR filled with methane was used as both a gas target and recoil detector. For the analyzing-power measurements the scattered neutron was detected in scintillation counters in coincidence with the recoil proton detected in IKAR. Special care was taken to ensure a precise absolute normalization of the cross sections, with overall systematic uncertainties of 4–7%.
