Available in PDF, EPUB and Kindle. Book excerpt: DOI: http://dx.doi.org/10.1016/j.physletb.2008.08.037 We calculate Ay in neutron-proton scattering for the interactions models WJC-1 and WJC-2 in the Covariant Spectator Theory. We find that the recent 12 MeV measurements performed at TUNL are in better agreement with our results than with the Nijmegen Phase Shift Analysis of 1993, and after reviewing the low energy data, conclude that there is no Ay problem in low-energy np scattering.

Available in PDF, EPUB and Kindle. Book excerpt: There have been few measurements of cross sections for neutron-proton scattering and radiative capture below 1 MeV. Those measurements which do exist are at a small number of energies and are often inconsistent with theoretical models and with each other. We have conducted several experiments with the goal of obtaining improved data on these cross sections at the University of Kentucky (UKY) and the Los Alamos Neutron Science Center (LANSCE). Feasibility studies for measuring the low energy cross section for np radiative capture have been conducted at both UKY and LANSCE, culminating in a measurement of the cross section at 0.5, 0.9, 1.5, 2.0, and 2.5 MeV at UKY, using a plastic scintillator to detect recoiling deuterons and two BGO scintillators to detect the [gamma]-ray yields at 64.6° and 106.6°. We also performed measurements of the response of BC418 plastic scintillator to low energy protons during these studies, and conducted several additional measurements of the scintillator response at LANSCE and UKY, yielding very precise results from 100 keV to 3.6 MeV. The total cross section for np scattering was measured at UKY from 150 to 800 keV by neutron transmission, measuring the neutron yields in a liquid scintillator with various targets in the beam. The cross section was determined by taking ratios of neutron yields with and without the target, giving cross sections which are independent of detector efficiency and dead time. These results fill a significant gap in the available data below 500 keV.

Available in PDF, EPUB and Kindle. Book excerpt: A completely model-independent effective range theory fit to available, unpolarized, np scattering data below 3 MeV determines the zero-energy free proton cross section [sigma][sub 0] = 20.4287 [+-] 0.0078 b, the singlet apparent effective range r[sub s] = 2.754 [+-] 0.018[sub stat] [+-] 0.056[sub syst] fm, and improves the error slightly on the parahydrogen coherent scattering length, a[sub c] = -3.7406 [+-] 0.0010 fm. The triplet and singlet scattering lengths and the triplet mixed effective range are calculated to be a[sub t] = 5.4114 [+-] 0.0015 fm, a[sub s] = -23.7153 [+-] 0.0043 fm, and [rho][sub t](0,-[epsilon][sub t]) = 1.7468 [+-] 0.0019 fm. The model-independent analysis also determines the zero-energy effective ranges by treating them as separate fit parameters without the constraint from the deuteron binding energy [epsilon][sub t]. These are determined to be [rho][sub t](0,0) = 1.705 [+-] 0.023 fm and [rho][sub s](0,0) = 2.665 [+-] 0.056 fm. This determination of [rho][sub t](0,0) and [rho][sub s](0,0) is most sensitive to the sparse data between about 20 and 600 keV, where the correlation between the determined values of [rho][sub t](0,0) and [rho][sub s](0,0) is at a minimum. This correlation is responsible for the large systematic error in r[sub s]. More precise data in this range are needed. The present data do not event determine (with confidence) that [rho][sub t](0,0) [ne] [rho][sub t](0, -[epsilon][sub t]), referred to here as ''zero-energy shape dependence''. The widely used measurement of [sigma][sub 0] = 20.491 [+-] 0.014 b from W. Dilg, Phys. Rev. C 11, 103 (1975), is argued to be in error.
