Experimental measurements of differential cross-sections for neutron-proton scattering are reported for 12 incident neutron energies between 28 and 75 MeV. Data are compared with predictions of different theoretical models and with other experimental results.

Measurement of spin-dependent total cross-section difference $\Delta\sigma_T$ in neutron-proton scattering at 16 MeV

Broz, J. ; Cerny, J. ; Dolezal, Z. ; et al.

Inspire Record 397734 DOI 10.17182/hepdata.31421

A new measurement of $\Delta\sigma_T$ for polarized neutrons transmitted through a polarized proton target at 16.2 MeV has been made. A polarized neutron beam was obtained from the $^{3}\rm{H}(d,\vec n)^{4}\rm{He}$ reaction; proton polarization over 90\% was achieved in a frozen spin target of 20 cm$^3$ volume. The measurement yielded the value $\Delta\sigma_T=(-126\pm21\pm14)$ mb. The result of a simple phase shift analysis for the $^3S_1-^3D_1$ mixing parameter $\epsilon_1$ is presented and compared with the theoretical potential model predictions.

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.

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.
