Polarization Analyzing Power Ay (theta) in pp Elastic Scattering at 643, 787, and 796 MeV

Bevington, P.R. ; McNaughton, M.W. ; Willard, H.B. ; et al.

Data have been obtained for the polarization analyzing power Ay(θ) in pp elastic scattering from near 30° to 90° (c.m.) at 643, 787, and 796 MeV. Relative uncertainties are typically ± 0.003 with an overall normalization uncertainty of {+1}{−0.5}%. Data are not consistent with existing phase-shift analyses.

THE ENERGY DEPENDENCE OF THE 90-degrees P P ELASTIC SCATTERING DEPOLARIZATION PARAMETER AND AMPLITUDES BETWEEN 0.9-GEV/C AND 1.5-GEV/C

Hollas, C.L. ; Cremans, D.J. ; Ransome, R.D. ; et al.

The depolarization parameter D NN for pp elastic scattering at θ cm = 90 ° has been measured at twelve momenta between 0.9 and 1.5 GeV/ c . The moduli of the three transversity amplitudes T 1 , T 3 , and T 4 have been extracted from these data and from previous measurements of the differential cross section and spin correlation parameter A NN (90 °). Smooth energy dependence is found for all three amplitude moduli.

Absolute p p elastic cross-sections from 492-MeV to 793-MeV using CH-2 targets

Simon, A.J. ; Glass, G. ; McNaughton, M.W. ; et al.
Phys.Rev.C 53 (1996) 30-34, 1996.
Inspire Record 429629 DOI 10.17182/hepdata.25831

pp-elastic differential cross sections are reported at 492 MeV from 40° to 90°, and at 576, 642, 728, and 793 MeV from 75° to 90° c.m., with an absolute accuracy of less than 1%. These data, obtained with polyethylene targets, agree with recent measurements at the same energies obtained with a liquid-hydrogen target. © 1996 The American Physical Society.

Absolute p p elastic cross-sections from 492-MeV to 793-MeV

Simon, A.J. ; Glass, G. ; McNaughton, M.W. ; et al.
Phys.Rev.C 48 (1993) 662-675, 1993.
Inspire Record 363783 DOI 10.17182/hepdata.26001

Absolute pp-elastic-differential cross sections were measured at incident energies 492, 576, 642, 728, and 793 MeV from about 30° to 90° c.m. The total uncertainty was determined to be less than 1%, made possible by particle counting for beam normalization and extensive cross-checks of systematic effects. These new data are consistent with previous data above 600 MeV but have uncertainties about a factor of 10 smaller. Near 500 MeV these data are consistent with 90° data from TRIUMF, but differ significantly from similar data from PSI; the cause of this discrepancy is discussed.

Polarization Measurements in pi+ p Elastic Scattering from 0.6-GeV/c to 2.65-GeV/c

Martin, J.F. ; Sleeman, J.C. ; Brown, Robert M. ; et al.
Nucl.Phys.B 89 (1975) 253-286, 1975.
Inspire Record 90870 DOI 10.17182/hepdata.6743

This paper presents the results of a counter experiment at the Rutherford Laboratory, in which the polarization parameter in π + p elastic scattering was measured. Data were taken at 64 incident pion momenta between 0.60 and 2.65 GeV/ c . The results are found to be in generally good agreement with those of other experiments, and have substantially higher precision at many momenta.
