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.

Vector analyzing power iT11 in pi d elastic scattering at 49 MeV

Kohler, M. ; King, B.E. ; Stevenson, N.R. ; et al.
Phys.Rev.C 49 (1994) 1715-1717, 1994.
Inspire Record 389448 DOI 10.17182/hepdata.25990

Measurements of the vector analyzing power iT11 in πd elastic scattering at 49 MeV have been performed using a dynamically polarized target and a magnetic spectrometer. Data at seven π+ laboratory scattering angles between 50° and 130° were taken together with a complementary measurement at 60° for π−d elastic scattering. In general, we find agreement with models that include the πN P11 amplitude and disagreement with models that exclude or suppress it.

Absolute differential cross-sections and charge asymmetries for pi+- d elastic scattering at 30-MeV, 50-MeV and 65-MeV

Kohler, M.D. ; Ristinen, R.A. ; Kraushaar, J.J. ; et al.
Phys.Rev.C 48 (1993) 1884-1889, 1993.
Inspire Record 365225 DOI 10.17182/hepdata.26004

Absolute π±d differential cross sections and charge asymmetries have been measured at incident pion energies of 30 and 50 MeV, using an active target of scintillator plastic to detect recoil deuterons in coincidence with scattered pions. In addition, a small set of data at 65 MeV was collected for comparision with the results of an earlier experiment performed by this group. Measurements at 50 MeV from the earlier experiment are compared with the results of the present experiment.

Absolute differential cross-sections and charge asymmetries for pi+- d elastic scattering at 65-MeV

Kohler, M.D. ; Brack, J.T. ; Clausen, B. ; et al.
Phys.Rev.C 44 (1991) 15-23, 1991.
Inspire Record 323111 DOI 10.17182/hepdata.26104

Absolute π±d differential cross sections and charge asymmetries have been measured at an incident pion energy of 65 MeV, using an active target of deuterated scintillator plastic to detect recoil deuterons in coincidence with scattered pions. Statistical and systematic uncertainties in the cross sections are each typically ±3%. The charge asymmetry is consistent with theoretical predictions.

Energy Dependence of the Charge Asymmetry a ($T (\pi$), $\theta$) in $\pi d$ Elastic Scattering

Smith, G.R. ; Gill, D.R. ; Ottewell, D. ; et al.
Phys.Rev.C 38 (1988) 240-250, 1988.
Inspire Record 250814 DOI 10.17182/hepdata.26223

Angular distributions of charge asymmetry A(Tπ,θ), have been measured for πd elastic scattering. Data were obtained in the backward hemisphere for pion bombarding energies of 143, 180, 220, and 256 MeV. The results are compared with predictions employing different mass and width parameters for the delta isobars.
