Polarization observables in pi d (polarized) elastic scattering: Analyzing powers tau (22) and iT (11) in the forward hemisphere

Wessler, M. ; Boschitz, E. ; Brinkmoeller, B. ; et al.
Phys.Rev.C 51 (1995) 2575-2583, 1995.
Inspire Record 405002 DOI 10.17182/hepdata.25896

The vector analyzing power iT11 and the composite observable τ22=T22+T20/ √6 were measured at 10 incident pion energies between 100 and 294 MeV, in an angular range between 50° and 120°. Two different techniques were applied, the detection of the pion with a magnet spectrometer, and the πd coincidence method with scintillation counters. In the case of the first technique also two different target materials were used. Consistency among all data was obtained. The experimental data are compared to Faddeev calculations from one of us (H.G.). The discrepancies between theory and experiment are discussed, and an outlook for further research is given.

Energy dependence of the spin-spin correlation parameter $C_{NN}$ at 50° and 90° c.m. for pp-elastic scattering in the energy range 0.69–0.95 GeV

Efimovyh, V.A. ; Kovalev, A.I. ; Poljakov, V.V. ; et al.
Phys.Lett.B 99 (1981) 28-32, 1981.
Inspire Record 1389635 DOI 10.17182/hepdata.27135

The spin-spin correlation parameter C NN at 50° and 90° c.m. for elastic pp-scattering has been obtained in the energy range 0.69–0.95 GeV. It was found that the parameter C NN (90°) shows resonance-like structure at energies near 700 MeV. Its energy dependence does not agree with Hoshizaki's phase-shift analysis predictions. C NN (50°) agrees well with these predictions and does not show any structure within the accuracy of the measurements.

Measurements of spin rotation parameter A in pion proton elastic scattering at 1.62-GeV/c.

The ITEP-PNPI collaboration Alekseev, I.G. ; Budkovsky, P.E. ; Kanavets, V.P. ; et al.
Phys.Lett.B 485 (2000) 32-36, 2000.
Inspire Record 526552 DOI 10.17182/hepdata.41744

The ITEP-PNPI collaboration presents the results of the measurements of the spin rotation parameter A in the elastic scattering of positive and negative pions on protons at P_beam = 1.62 GeV/c. The setup included a longitudinally-polarized proton target with superconductive magnet, multiwire spark chambers and a carbon polarimeter with thick filter. Results are compared to the predictions of partial wave analyses. The experiment was performed at the ITEP proton synchrotron, Moscow.

The ITEP-PNPI collaboration presents the first results of the spin rotation parameter A + measurements in the second resonance region. The experiment was performed at the ITEP accelerator at a positive pion beam momentum 1.43 GeV/c for scattering angles θ cm = 127° and 133°. The setup was based on a polarized proton target and a carbon-plate polarimeter. The obtained data is compared with the predictions of the existing partial-wave analyses.

Measurement of the total cross-section difference Delta(sigma-L) in n p transmission at 1.19-GeV, 2.49-GeV and 3.65-GeV

Results of the total cross section differenceΔσL in anp transmission experiment at 1.19, 2.49 and 3.65 GeV incident neutron beam kinetic energies are presented. Measurements were performed at the Synchrophasotron of the Laboratory of High Energies of the Joint Institute for Nuclear Research in Dubna. Results were obtained with a polarized beam of free quasi-monochromatic neutrons passing through the new Dubna frozen spin proton target. The beam and target polarizations were oriented longitudinally. The present results were obtained at the highest energies of free polarized neutrons that can be reached at present. They extend the energy range of existing results from PSI, LAMPF and Saclay measured between 0.066 and 1.10 GeV. The new results are compared withΔσL(pn) data determined as a difference betweenΔσL(pd) andΔσL(pp) ANL-ZGS measurements. The values ofΔσL for the isospin stateI=0 were deduced using knownpp data.
