“…The total angular momentum for the NN interaction used in the calculations was j ~< 3. At 8.0 MeV the data of Schwartz et al [8], Janson et al [9] and Seagrave et al [10] are in excellent agreement. The agreement between the data at 10.0 MeV is good but not quite as good as at 8.0 MeV.…”

“…The agreement between the data at 10.0 MeV is good but not quite as good as at 8.0 MeV. Since the data of Schwartz et al [8] were measured at 10.25 MeV, they should be about 27o lower, according to 3N calculations, than the 10.0 MeV data of Amten et al [11]; implying that either the data of Schwartz et al [8] are systematically slightly high or the data of Amten et al [11] are low. The discrepancy between the data becomes more obvious at 14 MeV.…”

Resolution of discrepancy between backward angle cross-section data for neutron-deuteron elastic scattering

Abstract. High-accuracy differential cross-section data for neutron-deuteron elastic scattering at centre-of-mass backward angles in the range from 140 ~ to 178 ~ have been measured to accuracies better than _+ 3% for incident neutron energies of 8.0, 10.0, and 14.0 MeV. The measurements were made by detection of the recoil deuterons and protons from a mixed CD2-CH 2 foil. The new data are compared to existing data and to three-nucleon calculations with the Bonn-B nucleon-nucleon potential. We conclude that the present measurements unambiguously resolve the discrepancies among previously reported data of the same type.

Polarization observables in neutron-deuteron scattering are calculated to next-to-next-to-nextto-leading order (N 3 LO) in pionless effective field theory (EFT π ). At N 3 LO the two-body P -wave contact interactions are found to be important contributions to the neutron vector analyzing power, A y (θ), and the deuteron vector analyzing power, iT 11 (θ). Extracting the two-body P -wave EFT π coefficients from two-body scattering data and varying them within the expected EFT π theoretical errors provides results that are consistent (at the N 3 LO level) with A y experimental data at low energies. Cutoff dependence of the N 3 LO correction to the doublet S-wave nd scattering amplitude suggests the need for a new three-body force at N 3 LO, which is likely one that mixes Wignersymmetric and Wigner-antisymmetric three-body channels. *

“…Former investigations of the elastic p-d scattering did not emphasize the very small forward and extreme backward angles sensitive to the Coulomb interaction [10,11,12]. The recent improved n-d results of the cross section and the analyzing power [4,13,14,15] prompt a comparison to new and improved p-d data. In particular the extreme backward angles cross sections of p-d scattering as compared to n-d scattering should be useful in checking the validity of any theoretical method of introducing Coulomb corrections into Faddeev calculations [9].…”

Measurement of $$D(\vec p,p)D$$ elastic scattering at 10.0, 12.0, 14.1 and 16.5 MeV especially for small forward and extreme backward scattering angles

Abstract. The D(ff, p)D elastic scattering was investigated especially in theCoulomb sensitive scattering regions. Angular distributions of the differential cross section and of the analyzing power Ay, with emphasis on small scattering angles, were measured at 10.0 and 14.1 MeV. For extreme backward angles up to ~.m. = 179~ the differential cross section was measured at 12o0, 14.1 and 16.5 MeV. The data have been compared with recent Faddeev calculations based on the realistic meson-exchange Paris potential and including an approximate Coulomb correction. There are discrepancies between the data and the calculations especially for the analyzing power. This indicates that the approximate treatment of Coulomb effects and possibly also the purely rmclear part of the calculations need to be improved.
