Inspire Record 285139 DOI 10.17182/hepdata.23146

A direct experimental reconstruction of the five complex pp elastic-scattering amplitudes has been performed at 447, 497, 517, 539, and 579 MeV. The reconstruction is done over the c.m. angles from 38° to 90° and is based on either 11 or 15 spin observables depending on the angular range. The reconstructed amplitudes are presented and compared to phase-shift analysis. A smooth energy behavior is observed for the amplitudes.

The polarization parameter Pn000, the two-spin parameters Dn0n0, Kn00n, Ds0s0, Ds0k0, and the three-spin parameters Ms0sn and Ms0kn have been measured for pp elastic scattering between 34° and 118° center-of-mass scattering angle at six different incident kinetic energies 447, 473, 497, 517, 539, and 560 MeV. The experiment was performed at SIN using a polarized proton beam, a polarized butanol target, and a polarimeter for the measurement of the polarization of the scattered proton.

Measurement of the Spin Correlation Parameters a(00kk), a(00ks) and a(00ss) in the p p Elastic Scattering Between 400-MeV and 600-MeV

Aprile, E. ; Hausammann, R. ; Heer, E. ; et al.
Phys.Rev.D 28 (1983) 21-39, 1983.
Inspire Record 162345 DOI 10.17182/hepdata.23773

We have measured the spin-correlation parameters A00kk, A00ks, and A00ss in p−p scattering between 400 and 600 MeV using a longitudinally polarized beam and a butanol target polarized in the horizontal plane. Owing to the restrictive geometrical acceptance of the target, the polarization axis of the target was oriented at an angle α with respect to beam direction. The parameters A00kk and A00ks were therefore measured as a linear combination at 577, 536, 514, 494, and 445 MeV. These experiments were extended to the measurement of A00ks and A00ss by using a transversely polarized beam. We present the results, which are compared with phase-shift predictions.

Direct Experimental Reconstruction of the $P P$ Elastic Scattering Matrix at 579-{MeV}

Aprile, E. ; Eisenegger, C. ; Hausammann, R. ; et al.
Phys.Rev.Lett. 46 (1981) 1047-1050, 1981.
Inspire Record 169865 DOI 10.17182/hepdata.20658

We have made, for the first time, a direct reconstruction of the pp elastic-scattering matrix at 579 MeV from a series of experiments performed at the Schweizerisches Institut für Nuklearforschung polarized-beam line. Fifteen observables consisting of the polarization, two-spin correlation and transfer parameters, and three-spin parameters were measured at seven angles between 66° and 90° (c. m.). The experimental results and reconstructed amplitudes are presented and compared to phase shift analysis.

The polarization parameter Pn000, the two-spin parameters Dn0n0, Kn00n, Ds0s0, and Ds0k0, and the three-spin parameters Ms0sn and Ms0kn have been measured for pp elastic scattering at 579 MeV between 34° and 118° center-of-mass scattering angle. The experiment was performed at SIN using a polarized proton beam, a polarized butanol target, and a polarimeter for the measurement of the polarization of the scattered proton. These data form the basis for a complete experimental determination of the scattering amplitudes.

Measurement of the Slope of the Diffraction Peak for Elastic pp Scattering from 8-GeV to 400-GeV.

Phys.Rev.Lett. 31 (1973) 1088-1091, 1973.
Inspire Record 81722 DOI 10.17182/hepdata.21381

The slope b(s) of the forward diffraction peak of p−p elastic scattering has been measured in the momentum-transfer-squared range 0.005≲|t|≲0.09 (GeV/c)2 and at incident proton energies from 8 to 400 GeV. We find that b(s) increases with s, and in the interval 100≲s≲750 (GeV)2 it can be fitted by the form b(s)=b0+2α′lns with b0=8.23±0.27, α′=0.278±0.024 (GeV/c)−2.

A Measurement of the Polarization Parameter in Backward pi- p Elastic Scattering at 3.5-GeV/c

Nucl.Phys.B 117 (1976) 77-94, 1976.
Inspire Record 110105 DOI 10.17182/hepdata.35603

The polarization parameter has been measured for π − p elastic scattering in the backward region at 3.5 GeV/ c incident momentum. The experimental set-up consisted of a polarized target in a spectrometer magnet, hodoscopes and wire spark chambers. Data are presented for the range −0.95< u ⩽−0.19 GeV 2 . An isospin analysis has been carried out to separate the I u = 1 2 and I u = 3 2 contributions.

A polarized proton beam extracted from SATURNE II was scattered on an unpolarized CH 2 target. The angular distribution of the beam analyzing power A oono was measured at large angles from 1.98 to 2.8 GeV and at 0.80 GeV nominal beam kinetic energy. The same observable was determined at the fixed mean laboratory angle of 13.9° in the same energy range. Both measurements are by-products of an experiment measuring the spin correlation parameter A oon .
