n p elastic analyzing power A(NO) and spin transfer K(NN)

McNaughton, M.W. ; Johnston, K. ; Swenson, D. ; et al.
Phys.Rev.C 48 (1993) 256-265, 1993.
Inspire Record 34401 DOI 10.17182/hepdata.51045

We have measured the analyzing power ANO and the spin transfer KNN for np-elastic scattering from about 60° to 170° c.m. at 485, 635, and 788 MeV. The new data clarify previous discrepancies and complete the first-order determination of nucleon-nucleon elastic scattering at these energies.

Differential cross-section for n p elastic scattering in the angular region 50-degrees < Theta* < 180-degrees at 459-MeV

Northcliffe, L.C. ; Jain, M. ; Evans, M.L. ; et al.
Phys.Rev.C 47 (1993) 36-46, 1993.
Inspire Record 358672 DOI 10.17182/hepdata.26016

The differential cross section for n-p elastic scattering at 459 MeV in the c.m. angular region 50°<θ*<180° has been measured with high statistical precision and good relative accuracy. The uncertainty in the absolute normalization (based on the simultaneously measured yield of deuterons from the np→dπ0 reaction) was initially estimated to be ∼7%. The results agree well with back-angle data obtained independently at LAMPF but less well with results from Saclay and the Princeton-Pennsylvania Accelerator and, except for a normalization difference of 10%, are fairly well represented by a phase-shift fit. The pole-extrapolation method of Chew was used to extract the pion-nucleon coupling constant f2 from the back-angle portion of the data. The value obtained, f2=0.069, is somewhat smaller than the values 0.0735–0.0790 obtained from analyses of pion-nucleon scattering, tending to confirm the need for an upward renormalization of the angular distribution by ∼10%.

Measurement of C(ll) and C(sl) in $N P$ Elastic Scattering at 484-{MeV} and 634-{MeV}

Burleson, G.R. ; Faucett, J.A. ; Fontenla, C.A. ; et al.
Phys.Rev.Lett. 59 (1987) 1645, 1987.
Inspire Record 21907 DOI 10.17182/hepdata.3247

The spin-spin correlation parameters CLL=(L,L;0,0)=ALL and CSL=(S,L;0,0)=ASL for np elastic scattering were measured for incident polarized-neutron–beam kinetic energies of 484 and 634 MeV over the center-of-mass angles from ≃80° to 180°. The data are important for determining the I=0 nucleon-nucleon amplitudes. These results are compared with phase-shift calculations.

SPIN DEPENDENCE IN NEUTRON PROTON CHARGE EXCHANGE AT 790-MEV

Ransome, R.D. ; Hollas, C.L. ; Riley, P.J. ; et al.
Phys.Rev.Lett. 48 (1982) 781-784, 1982.
Inspire Record 180615 DOI 10.17182/hepdata.20595

The analyzing power A and spin-transfer parameters KNN, KSS, KSL, and KLL have been measured in the np charge-exchange (np→pn) region at 790 MeV. These data provide new and unique information on the spin dependence of the np interaction in the charge-exchange region. Models which explain the charge-exchange peak in the np elastic differential cross section as being due to interference between one-pion exchange and a slowly varying background are in basic agreement with the data.

Neutron-Proton Charge-Exchange Scattering from 22-GeV/c to 65-GeV/c

Babaev, A. ; Brachman, E. ; Eliseev, G. ; et al.
Nucl.Phys.B 110 (1976) 189-204, 1976.
Inspire Record 100178 DOI 10.17182/hepdata.35776

The differential cross sections for neutron-proton elastic charge-exchange scattering have been measured with a two-arm technique for incident neutron momenta between 22 and 65 GeV/ c and for values of the momentum transfer squared between 0.002 and 0.8 (GeV/ c ) 2 . The sharp forward peak observed previously at lower energies is also present at momenta up to 65 GeV/ c ; however the s dependence of the cross section is slowing down.

N p Charge Exchange Scattering at Fermilab

Barton, H.R., Jr. ; Reay, N.W. ; Reibel, K. ; et al.
Phys.Rev.Lett. 37 (1976) 1656, 1976.
Inspire Record 112288 DOI 10.17182/hepdata.21058

We have measured the neutron-proton charge-exchange differential cross section in the momentum interval 60 to 300 GeV/c, with squared four-momentum transfers 0.002 to 0.8 (GeV/c)2. Independent of incident momentum, the data are characterized by a sharp forward peak of width 0.02 (GeV/c)2, followed by a shoulder and gentler falloff at higher momentum transfers.
