Neutron-Proton Differential-Cross-Section Measurements at 50 MeV

Montgomery, T.C. ; Brady, F.P. ; Bonner, B.E. ; et al.
Phys.Rev.Lett. 31 (1973) 640-643, 1973.
Inspire Record 945159 DOI 10.17182/hepdata.21337

The neutron-proton differential cross section at 50.0 MeV has been measured to a precision of ≃ 2% for backward-hemisphere c.m. angles and ≃ 3% for forward angles, both relative. The present data are not in good agreement with the previous n−p measurements near this energy. A preliminary phase-shift analysis using the present data produces more satisfactory results, particularly for the P11 phase shift.

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.

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.
