Determination of Proton Nucleon Analyzing Powers and Spin Rotation Depolarization Parameters at 500-{MeV}

Marshall, J.A. ; Barlett, M.L. ; Fergerson, R.W. ; et al.
Phys.Rev.C 34 (1986) 1433-1438, 1986.
Inspire Record 240068 DOI 10.17182/hepdata.26283

500 MeV p→+p elastic and quasielastic, and p→+n quasielastic, analyzing powers (Ay) and spin-rotation-depolarization parameters (DSS, DSL, DLS, DLL, DNN) were determined for center-of-momentum angular ranges 6.8°–55.4° (elastic) and 22.4°–55.4° (quasielastic); liquid hydrogen and deuterium targets were used. The p→+p elastic and quasielastic results are in good agreement; both the p→+p and p→+n parameters are well described by current phase shift solutions.

Neutron-proton elastic scattering from 5 to 30 gev/c

Gibbard, B.G. ; Longo, M.J. ; Jones, Lawrence W. ; et al.
Nucl.Phys.B 30 (1971) 77-115, 1971.
Inspire Record 68614 DOI 10.17182/hepdata.33298

The differential cross section for neutron-proton elastic scattering was measured in the diffraction region with incident neutron momenta between 5 and 30 GeV/ c . The experiment was an optical-spark-chamber-counter experiment conducted at the Brookhaven National Laboratory alternating gradient synchrotron. A well collimated neutron beam with a broad energy spectrum was incident on a liquid hydrogen target. The scattered neutrons were detected in a thick-plate spark-chamber array while the recoil protons were detected and momentum analyzed in a magnetic spectrometer with thin-foil spark chambers.

ANALYZING POWER IN LARGE ANGLE PROTON NEUTRON ELASTIC SCATTERING

Makdisi, Y. ; Marshak, M.L. ; Mossberg, B. ; et al.
Phys.Rev.Lett. 45 (1980) 1529-1533, 1980.
Inspire Record 159455 DOI 10.17182/hepdata.20701

The large-angle analyzing power A in proton-neutron elastic scattering at 2, 3, and 6 GeV/c with use of the polarized proton beam at the Argonne zero-gradient synchrotron and a liquid deuterium target have been measured. The measurements, the first at high energy, show that A is large (20-40%) and negative over much of the angular range and shows no decrease with incident energy, unlike the earlier data at smaller angles.
