Backward n p scattering with a polarized target

Robrish, P.R. ; Chamberlain, O. ; Field, R.D. ; et al.
Phys.Lett.B 31 (1970) 617-620, 1970.
Inspire Record 63165 DOI 10.17182/hepdata.5937

We measured the polarization parameter P in neutron-proton elastic scattering near the backward direction, using a polarized proton target. Measurements covered the range of incident neutron momenta from 1.0 to 5.5 GeV/ c and of four-momentum transfer squared u from −0.005 to −0.5 (GeV/ c ) 2 .

Angular dependence of the beam and target analyzing powers a(oono) and A(ooon) in n p elastic scattering between 0.477-GeV and 0.940-GeV

Ball, J. ; Chesny, P. ; Combet, M. ; et al.
Nucl.Phys.A 559 (1993) 477-488, 1993.
Inspire Record 33734 DOI 10.17182/hepdata.36610

We present a total of 273 independent data points of the analyzing powers A oono (nP) and A ooon (nP) in a large angular interval at four energies between 0.477 and 0.940 GeV. The SATURNE II polarized beam of free neutrons obtained from the break-up of polarized deuterons was scattered on the polarized Saclay frozen-spin proton target. Part of the data was obtained with a CH 2 target. A comparison of the two measured observables allows one to determine the polarization of the neutron beam. The present results provide an important contribution to any future theoretical or phenomenological analysis.

Angular dependence of analyzing power in n p elastic scattering between 0.312-GeV and 1.1-GeV

Nucl.Phys.A 559 (1993) 489-510, 1993.
Inspire Record 341321 DOI 10.17182/hepdata.36590

We present a total of 427 np analyzing power data points in a large angular interval at 12 energies between 0.312 and 1.10 GeV. The SATURNE II polarized beam of free monochromatic neutrons was scattered either on the Saclay frozen-spin polarized proton target or on CH 2 and C targets. Present results are compared with existing elastic and quasieleastic data.

Analyzing Powers in Free $N$ (Polarized) $P$ Forward Elastic Scattering at Energies From 630-{MeV} to 1000-{MeV}

Korolev, G.A. ; Khanzadeev, A.V. ; Petrov, G.E. ; et al.
Phys.Lett.B 165 (1985) 262-264, 1985.
Inspire Record 228528 DOI 10.17182/hepdata.30310

The analysing powers in free →n p forward elastic scattering have been measured for incident neutron energies of 633, 784, 834, 934 and 985 MeV, and for momentum transfer 0.01 < ‖ t ‖ < 0.10 ( GeV / c ) 2 . The experiment used a recoil detector ionisation chamber which served at the same time as a gas target, and scintillation counters to measure the asymmetry of the scattered neutrons.

MEASUREMENT OF THE POLARIZATION PARAMETER IN 24-GeV/c PROTON NEUTRON ELASTIC SCATTERING

Crabb, D.G. ; Kyberd, P. ; Salmon, G.L. ; et al.
Nucl.Phys.B 201 (1982) 365-382, 1982.
Inspire Record 181092 DOI 10.17182/hepdata.34198

The polarization parameter in pn elastic scattering has been measured at 24 GeV/ c over the range of four-momentum transfer squared 0.1 < | t | < 1.25 (GeV/ c ) 2 , and found to be negative except for a zero at | t | = 0.65 (GeV/ c ) 2 .

EXPERIMENTAL STUDY OF POLARIZATION IN THE REACTION ANTI-P P ---> ANTI-P P AT 0.7-GeV/c

Kimura, M. ; Takanaka, M. ; Hamatsu, R. ; et al.
Nuovo Cim.A 71 (1982) 438-444, 1982.
Inspire Record 184275 DOI 10.17182/hepdata.37469

The polarization for the\(\bar pp\) elastic scattering was measured as a function of the centre-of-mass angle of scattering between 17° and 90° at the average incident momentum of 0.7 GeV/c by using doublescattering events in a bubble chamber. The average value of the polarization was found to be 0.23 ± 0.05. The angular dependence of the polarization obtained in this experiment was interpreted by the strong absorptive potential model for\(\bar {\mathcal{N}}{\mathcal{N}}\) interactions recently proposed.

Polarization measurement of antiproton scattered elastically from proton at 220 mev

Ohsugi, T. ; Fujisaki, M. ; Kaneko, S. ; et al.
Nuovo Cim.A 17 (1973) 456-463, 1973.
Inspire Record 87646 DOI 10.17182/hepdata.37771

The polarization of scattered antiproton in\(\bar pp\) elastic scattering has been measured at the kinetic energy of 220MeV by means of double scattering in a bubble chamber. The polarizations obtained are 0.28±0.11, 0.46±0.12, 0.51±0.19 and 0.38±0.31 at the scattering angles 28°, 42°, 56° and 73° in the c.m. system, respectively. These results do not seem to be in good agreement with a prediction given by Bryan and Phillips. We have also compared these data with a modified diffraction model.

The vector analyzing power has been measured for π+d elastic scattering at 0.74 GeV/c in the angular range of thetac.m.=40?(de–105°, using a polarized deuteron target in a large aperture spectrometer. A comparison with calculations based on the Glauber model was made.

Test of Charge Symmetry in Neutron - Proton Elastic Scattering at 477-{MeV}

Abegg, R. ; Bandyopadhyay, D. ; Birchall, J. ; et al.
Phys.Rev.Lett. 56 (1986) 2571, 1986.
Inspire Record 228239 DOI 10.17182/hepdata.20237

An experiment resulting in the first measurement of the isospin-mixing, charge-symmetry-violating component of the n−p interaction has been performed. The experiment determined the difference in the angles of the zero crossing of the neutron and proton analyzing powers An and Ap at 477 MeV. In terms of the laboratory scattering angle of the neutron, the measured difference is θ0n(An)−θ0n(Ap)=+0.13° ±0.06° (±0.03°), where the second error is a worst-case estimate of systematic error. The resulting difference in the analyzing powers at the zero-crossing angle is An−Ap=+0.0037 ±0.0017 (±0.0008).
